So, the flame restoration method is known as flame polishing, and it works with acetal plastics, like Delrin. It works really great with acrylic to make cut edges look like pure and clean glass.
Doesn't really work much with cat in it....the excess fuel just get caught in the cat and burns off. Bad for it yes... Blows it.. Would take a lot of them. For the exhaust... That's just theory... If it does damage to your exhaust there would have to be a weak point already. Imagine the different between anti lag pressure and on shitty keypop and there exhausts stay on 😂
14:43 definitely works, but only on PVC plastic. The semi soft stuff used on old dirt bikes and quads. HOWEVER…. There’s a better process. Use the finest grit sand paper you can find, polish off the oxidation, and use a heat gun, which has significantly more control.
Only potential issue I see there is that even the finest grit could sand away the texture of the part. The heat gun seems certainly like a more controllable option.
James, turn the quart of oil around backwards when pouring. This will ventilate bottle and give you a smooth and consistent stream, as well as allowing you to get the spout closer to the oil fill point in most cases. -Dad

To get a new 1qt bottle of oil pour started… pour it sideways (front label facing towards the fill hole). This will allow 2 things: 1. The spout can get a lot closer to the hole before the oil comes out. & 2. You’ll get a nice even pour with a steady air flow (no air gulping).

Yeah, I'd rather just use other compounds that I already use to clean my car, there are paint products which work, and can seal it at the same time. As they said, it compromises the plastic and only lasts for so long, then you have to replace it.
I don't know how long it lasts but it's definitely temporary, you'd be better off painting it with something more uv resistant but I think it'd have a different finish than normal plastic
True story: While I was going though flight training, one of the pre-flight tests is a magneto loss test. You have two mags and swap between both and only one. Problem is the same key switch also goes all the way to ignition OFF. I was nervous the first time and gave it a little too much oomph and went right past R and L and straight to OFF. I immediately realized I screwed up and flipped it back to one of the running states and it backfired something fierce. Shook the whole plane.
The antilag hack is known as “keybang”, they work on older “carburetor” cars since there is no ECU to control the fuel going through the engine when you shut it off, and basically the engine is still kinda running when the switch is OFF but the fuel isn’t ignited, goes into your tail pipe, and when you switch back ON, BOOM! EFI cars basically shuts the fuel pump (when you turn the car off) so there is no Bang….
@@persil98 I cant say tho, cuz the ECU of stock EFI vehicles tend to cut off the fuel when ignition is turned off. Now an standalone ecu could let this happen, cuz thats where 2 step comes into play, 2 step and antilag basically limits your RPMs by cutting the ignition, and let the fuel go into tailpipe without igniting it, so the force induction systems can be fully spooled (in case of turbos) at a limited Rpm, and eventually you’ll get bangs cuz that fuel is ignited!

For the black plastic that’s faded, if you melt coconut oil and use a paper towel to spread it on, it makes the plastic pretty and black for a month or so, depending on how much sun the car gets
The plastic trick works, and I use it frequently detailing. You need to use a heat gun, a torch is too much. It doesn't work with very thick plastic very well though.
It’s also used on plastic stadium seats, but the key there is also a much slower billowing flame. You don’t want a ton of heat blowing too quickly at it, you just need the heat to barely lick the surface so it melts and refreezes the plastic quickly, which will refinish the surface since the grime and oxidation will burn right off as it happens
Question, how do you protect the paint? Do you need to? I've thought about doing this to my car but I'm concerned the paint near the plastic will bubble or peel.
We restored all the plastic on an old four wheeler to almost like new condition with this hack saving a massive amount of cash. We used both a torch and a heat gun and while I agree the torch can be a bit trickier I found it gave us a deeper shine in the end but probably could get that with the heat gun with a little more work. Torch was just faster and I'm impatient!
@@neonlights_12 If you dont stay on the same place with the heat to long the paint is ok. I have done it a couple of times but with a heat gun, never hurt the paint. It just takes a little more time
15:00 the proper way to do this is with a drill and a buffing attachment, dont put on any coumpound and build up tha friction, that way it only melts the very top layer, doing it with a blowtorch will make the plastics brittle
A little bit of compound helps with the burn you can get with buffing, preferably hit it after you spur off your pad between sections. Drills dont have enough rpm to get that shine needed, you need a buffer IMO
Also I'm sure it depends on the gas that you use; propane versus butane. I believe butane burns a ton hotter, so propane is the way to go. I've seen videos of this working on sun damaged stadium bleacher seats using a larger flamethrower nozzle and further distance from the nozzle in the plastic resulting in lower heat. Makes me wonder if this might work done fogged up headlights 🤔
The tennis ball works because of heat generated from friction similar to a buffer. The fibers might help like rubbing compound. You can’t get too hot cause you can do damage though.
Love the exhaust pop. Some years ago, my buddy was driving his dads Chrylsler. He showed me how he could make the car pop by putting it in N while going 55 on the highway, turning the key to off and then back on. Blew the muffler and tail pipe off!
The antilag hack would work with a carbed engine, since the air flow would still suck gas despite the electric switch state being off. As soon as you turn on the switch there will be an excess of unburned gas inside the exhaust.
Anyone reading this, for god's sake don't do this to a car. You can bend a valve, warp the throttle body, even blow a converter or muffler off the car. It's about as smart as dropping a small bomb in the intake. A single backfire, (this is an intake backfire) can do thousands of dollars worth of damage. Oh and on a vehicle with a carb it will often burn the car to the ground. You just threw fire at a carburetor full of gasoline.
I was going to say the same thing. Local hoons love doing key bangers at 3am. Sounds like a gun shot, that is not a common thing to hear in urban Australia.
Tbf I've seen another YTer, Torque Steer, use the heating trim method but using a heat gun instead of a handheld blow torch and it worked wonders for his car
@@wyckedan for him it did last longer but it also be because of different climates. The TikTok was most likely done in the US whereas Torque Steer is in the UK, and we end up getting less direct sunlight than the US a lot of the year
I've taken a lid to an old gallon oil container and drilled a hole in it, stuck a piece of clear rubber hose through the hole and JB welded the shit out of it. Put the lid on a new bottle of oil, stick the hose in the oil fill hole, turn it upside down and stab the bottom of the bottle, it fills up quick with no drips
The homemade antilag trick was really popular in the '80s. I used to live near a highway overpass and everyone would do it every time they drove under it.
The dipstick trick worked great for me topping off my ATF in my old Saturn because the fill point was super low in the engine bay and had a small hole.
For pouring oil: use key to put finger sized hole in bottle seal. Put finger over hole. Invert and place over fill. Remove finger and place bottle neck fully into filler neck. Squeeze bottle to increase flow release to bring air into bottle and squeeze again.
Regarding the Anti-Lag hack, this generally only works on cars with a Carburetor as opposed to EFI. As with a Carby, the fuel / air is mixed by purely mechanical actuation and passive fluid dynamics, which continues even once the spark plug is disconnected. The combustible mixture will be passed out the exhaust valve and start to fill the tailpipe. The longer you have it 'off' for, or more you pump the gas, the bigger bang you get! This works extremely well on older cars, and in most cases if you overdo it, you will blow a hole in the muffler (permanently giving you that sweet aftermarket exhaust sound). In reality it sounds more like a backfire than an Anti-Lag system. It can be great fun if have a car you don't care about, and want to scare the crap out of anyone nearby!
@@znorrk2 yes, it need carburetor, you can add more fuel, when you turn engine off, pump gas and turn on the ingition. while driving it's easier. but it will blow up you'r exhaust, atleast muffler will be cut in half sooner or later.
@@znorrk2 Yea its at least a lot easier on carbs. I have done it with both my old moped and a kerosene/gasoline powered tractor. ;) (It blew the muffler like 10 meters behind me on the moped so i had to drive home without it late at night)
This works preferably on carb cars yes but some fuel injection motors also do it I know Ford rocam motor also does that like a boss and shoots 6 foot flames
the oil dipstick thing is actually super useful. my three piece oil pan leaks, go figure and I just top her off every week but get oil literally everywhere.
That whole "crackles and pops from the exhaust thing" back in the carbureted days you would push in the clutch, turn off the key, kick the gas pedal a couple times, turn the key back on then bump start it by dumping the clutch - key banger. That blow torch restore plastic thing, they do it on baseball stadium seats that fade; it works on a certain kind of plastic.
I have been watching this channel back you had 1 video a week. The fact that you put the time in to research stuff is amazing. I think everyone at Donut has to have a lot of fun as well as learn just as much getting out of there comfort zone with working on new things. Keep up the great content 👏.
I've done the torch months ago on my escape cladding and works amazingly well. 1st hold it 6inches away . 2nd move around alot . You can also use a heatgun
Back in the day with a carburetor, you'd shut off the key and then pump the gas a whole bunch, lift off the gas and turn on the key and run over your muffler when it blew off.
You don’t let me down man! I come here for good vibes and great vehicle information and fun. Whenever I’m having a bad day I can always count on your channel for positivity 👍👍
I’ve used the dipstick trick for topping up trans fluid in my 99 ram, couldn’t find a funnel small enough to fit in the dipstick tube and was too lazy to find one, threw in the dipstick and poured it in there, works great for small amounts
14:49 the do this to the plastic seats in stadiums etc too. the plastic basically starts cracking on the surface due to sun light and this basically "melts" the top layer of the plastic "repairing" the plastic
@@Mika-ph6ku Yeah. I was thinking about a specific F1 clip where the driver's steering wheel suddenly comes off when he's driving down the straight. He saved it by holding the column in one hand and got the wheel back on, then resumed racing.
Trim restore? Cerakote. I've used it on several parts and it's held up impressively well. My side mirrors have been shiny and black for the last ~2 years of sitting outside in direct sun so I can say it's not half bad.
the ignition cut crackle hack is an old school thing, works much better with a carburetor because the carb keeps putting fuel in when the ignition is cut. Re-ignition causes big KA-POW backfire.
The pop trick works best on carbs, used to do it from time to time on my dirt-bike (and it's even easier on bikes because they have kill-switches). Never managed to do it on fi.
Used to Keybang the shit outta my D16 i had in my Honda (we call it keybanging in the UK) and with a nice system it would shoot big flames which was always fun
11:48 fun fact if you do this with a carburetted vehicle while it's in motion you can literally detonate the muffler and cat. Raw unburned fuel/air charge will build up in these areas and when the engine fires back up again the resulting pops and bangs will be quite a bit bigger than expected. This happens because carburetted vehicles rely on physics rather than electronics to fuel themselves; any time the engine is rotating it is pulling fuel in and if it's not burning it that fuel gets pumped right back out again.
The ignition bang trick works great on a carburetated motorcycle. Just flip that kill switch on/off as you decelerate in gear and youll sound like a drive by
Yeah I don't think it works vehicles with electronic fuel injection. To work it requires fuel to be flowing to the cylinders while the ignition is is off - so carbs and maybe mechanical fuel injection.
I was making my 1978 Datsun pop like that back in the 80's. Id rev to about 5 grand, cut the power for a second and turn it right back on. Sometimes id get a small flame out the pipes. Yes, it works
Even though it did kinda work, in the first hack you can clearly see the guy scratch the rear passenger door (door panel gap between front and rear doors is on the right and rear wheel in picture) and after the cut the "fixed" panel is the front passenger door since you can see the reflection of the side mirror magically appear in the panel.
Known about the blowtorch trick since 2009, being in the Jeep community. I have done this with my own wrangler. It works. But like they said the correct plastic and the practice is what it takes.
6:03 Or! Hear me out here, you could realize that there is a reason that the opening to every oil bottle you've ever seen is on one side and not in the center. It's so that you can tip it, with the opening up top, and not spill oil everywhere. Literally every person I've ever seen put oil in their car, outside of people I've worked with in shops, does it wrong, and spills oil because of it.
small scratches tend to just fill back up with scooped paint when you rub them with towel or in that case tennis ball ....the scooped up paint (it doesnt vanish you scrath the paint off and it stays around the scratched channel) just returns into the groove you got on the laquer
I'm into 3d printing, ABS and PLA plastics Sometimes I sand the surface and hit it with a heat gun afterwards. When you have a surface layer of sanded bits like that the surface will pool itself when heated giving that fresh clean new look. There are chemical agents out there that do the same trick/hack/job. Not a scientist either, but love your vids. 👍🙏🤟
The torch thing does work I've done it on my dirt bike.. it's used to get the scratches and gouges smoothed back out. But you can mess it up quick if you have ocd... a heat gun works way better though

Love the exhaust pop. Some years ago, my buddy was driving his dads Chrylsler. He showed me how he could make the car pop by putting it in N while going 55 on the highway, turning the key to off and then back on. Blew the muffler and tail pipe off!
The antilag hack would work with a carbed engine, since the air flow would still suck gas despite the electric switch state being off. As soon as you turn on the switch there will be an excess of unburned gas inside the exhaust.
works on injection engine too if you have no catalytic converters
Did it with a 93 Dakota. Easier if you’re moving in gear. It did turn the muffler into one of those exploding joke cigars tho. Use with caution.
Anyone reading this, for god's sake don't do this to a car. You can bend a valve, warp the throttle body, even blow a converter or muffler off the car. It's about as smart as dropping a small bomb in the intake. A single backfire, (this is an intake backfire) can do thousands of dollars worth of damage.
Oh and on a vehicle with a carb it will often burn the car to the ground. You just threw fire at a carburetor full of gasoline.
@@benpeak5047 gunna try jt on my 2002 v8 dakota, it already cracks and pops just revving it
@@DownHillgamer my 1995 suzuki swift does it, very loud (geo metro in the USA)
that “anti-lag” hack is very common in australia, we just call it key banging
😂😂😂
I was going to say the same thing. Local hoons love doing key bangers at 3am. Sounds like a gun shot, that is not a common thing to hear in urban Australia.
Lotta 15 yo’s here in Sweden do that with their mopeds too haha
Works best with a Carby, and if you do it good enought, she will peel your exhaust box like a banana!
Same thing here in New Zealand, any old carby motor will key bang if you try haha
Tbf I've seen another YTer, Torque Steer, use the heating trim method but using a heat gun instead of a handheld blow torch and it worked wonders for his car
If had it work just fine both ways, the problem is it only lasts about a week
@@wyckedan for him it did last longer but it also be because of different climates. The TikTok was most likely done in the US whereas Torque Steer is in the UK, and we end up getting less direct sunlight than the US a lot of the year
@@wyckedan long enough if you're just selling your car 😁
@@wyckedan That's why you clear coat the plastic immediately after you do this.
@@wyckedan Keeps it looking great for much longer. You can do the same thing to headlights after polishing them.
The oil dipstick trick is actually great for pouring paint. Use a stir stick for house paint or like a skewer for model paints!
When I change my oil. I pour the first qt in and cut the bottom of the first qt bottle off and use it as a funnel
I've taken a lid to an old gallon oil container and drilled a hole in it, stuck a piece of clear rubber hose through the hole and JB welded the shit out of it. Put the lid on a new bottle of oil, stick the hose in the oil fill hole, turn it upside down and stab the bottom of the bottle, it fills up quick with no drips
@@lordowl3533 that's a great idea. I think I might do that instead

The homemade antilag trick was really popular in the '80s. I used to live near a highway overpass and everyone would do it every time they drove under it.
The dipstick trick worked great for me topping off my ATF in my old Saturn because the fill point was super low in the engine bay and had a small hole.
I used to do the “anti lag” pop all the time in my old civic. Driving through downtown I thought it was funny to scare people.

Aussies do keybanging the best
James when was last time that you say: " This is everything you need to know....." we all miss that.
about 2 weeks ago
For pouring oil: use key to put finger sized hole in bottle seal. Put finger over hole. Invert and place over fill. Remove finger and place bottle neck fully into filler neck. Squeeze bottle to increase flow release to bring air into bottle and squeeze again.
Regarding the Anti-Lag hack, this generally only works on cars with a Carburetor as opposed to EFI. As with a Carby, the fuel / air is mixed by purely mechanical actuation and passive fluid dynamics, which continues even once the spark plug is disconnected. The combustible mixture will be passed out the exhaust valve and start to fill the tailpipe. The longer you have it 'off' for, or more you pump the gas, the bigger bang you get!
This works extremely well on older cars, and in most cases if you overdo it, you will blow a hole in the muffler (permanently giving you that sweet aftermarket exhaust sound). In reality it sounds more like a backfire than an Anti-Lag system. It can be great fun if have a car you don't care about, and want to scare the crap out of anyone nearby!
The popping exhaust has worked for me, I have literally blown up an exhaust doing this, but it was deffo worth it :)
Now I wanna try it💀
I believe this only works on carbs, not injector vehicles.
@@znorrk2 yes, it need carburetor, you can add more fuel, when you turn engine off, pump gas and turn on the ingition. while driving it's easier. but it will blow up you'r exhaust, atleast muffler will be cut in half sooner or later.
@@znorrk2 Yea its at least a lot easier on carbs. I have done it with both my old moped and a kerosene/gasoline powered tractor. ;)
(It blew the muffler like 10 meters behind me on the moped so i had to drive home without it late at night)
This works preferably on carb cars yes but some fuel injection motors also do it I know Ford rocam motor also does that like a boss and shoots 6 foot flames

@bete pisan you are the reason industrial revolution caused disastrous effects
the oil dipstick thing is actually super useful. my three piece oil pan leaks, go figure and I just top her off every week but get oil literally everywhere.
That whole "crackles and pops from the exhaust thing" back in the carbureted days you would push in the clutch, turn off the key, kick the gas pedal a couple times, turn the key back on then bump start it by dumping the clutch - key banger.
That blow torch restore plastic thing, they do it on baseball stadium seats that fade; it works on a certain kind of plastic.

I've done the torch months ago on my escape cladding and works amazingly well. 1st hold it 6inches away . 2nd move around alot . You can also use a heatgun
That's terrible for the trim in the long run. You're much better off using a quality trim dressing.
Make sure it's also very clean, oil and stuf will leave nasty mark
The problem is the plastic underneath is now brittle, the heat just moves the oils around within the plastic
Dude these spam accounts are out of control ^^^^^

Potato knob requires a spud wrench to install

I blew up my muffler, shortly after learning the backfire hack. Gotta keep it floored, while the key is off.
Back in the day with a carburetor, you'd shut off the key and then pump the gas a whole bunch, lift off the gas and turn on the key and run over your muffler when it blew off.

To get exhaust bangs that way, it works best with carburetors. One sister did it with a vw bug and shot away the muffler.

I’ve used the dipstick trick for topping up trans fluid in my 99 ram, couldn’t find a funnel small enough to fit in the dipstick tube and was too lazy to find one, threw in the dipstick and poured it in there, works great for small amounts
9:25 OK, hear me out:
Someone should make an edit of the first Fast and Furious movie and replace every single gear-shift with a potato gear-shift.
8:06 Ireland, he's from Ireland, everyone uses spuds for everything here 🤣
The hack for anti lag is just called "key-banging" loads of boy racers in Ireland do it and it just ruins the engine
Doesnt ruin the whole engine just ur coil packs and that
Used to do that holding down the kill switch to make the old XR pop.
It also only works on carby engines not efi
@@macmitch5 have to kill the power to the coil packs instead of the ignition. Still works
@@macmitch5 You can do it with EFI it’s just a little harder
14:49 the do this to the plastic seats in stadiums etc too. the plastic basically starts cracking on the surface due to sun light and this basically "melts" the top layer of the plastic "repairing" the plastic
Whats worse than not having a shift knob?
James: ~litterally nothing~
Not having a steering wheel maybe?
@@pallemanden just slap a potato on the column and steer with 1 hand
@@Mika-ph6ku Yeah. I was thinking about a specific F1 clip where the driver's steering wheel suddenly comes off when he's driving down the straight. He saved it by holding the column in one hand and got the wheel back on, then resumed racing.
Uncle Jerry and Dave's commercials make me genuinely happy. I always make sure to watch them!
Trim restore? Cerakote. I've used it on several parts and it's held up impressively well. My side mirrors have been shiny and black for the last ~2 years of sitting outside in direct sun so I can say it's not half bad.
the ignition cut crackle hack is an old school thing, works much better with a carburetor because the carb keeps putting fuel in when the ignition is cut. Re-ignition causes big KA-POW backfire.
I always love seeing Joe in videos KEEP IT JUICED!!!
14:25 Works perfectly for me, but I use a heat gun. It isn't as intense an a blow torch. On my Hummer H3 I had to redo it after a year or so.
The pop trick works best on carbs, used to do it from time to time on my dirt-bike (and it's even easier on bikes because they have kill-switches). Never managed to do it on fi.
Used to Keybang the shit outta my D16 i had in my Honda (we call it keybanging in the UK) and with a nice system it would shoot big flames which was always fun
I managed to do it on my fuel injected Honda motorcycle. I discovered it by accident while riding.
Depends on the fi system, a lot of systems also kill the fuel system instead of just the ignition
ruclips.net/video/yQBnPT2rX2g/видео.html
11:48 fun fact if you do this with a carburetted vehicle while it's in motion you can literally detonate the muffler and cat. Raw unburned fuel/air charge will build up in these areas and when the engine fires back up again the resulting pops and bangs will be quite a bit bigger than expected. This happens because carburetted vehicles rely on physics rather than electronics to fuel themselves; any time the engine is rotating it is pulling fuel in and if it's not burning it that fuel gets pumped right back out again.
Love when James says: As we know jetta is a race car..."😅😅😅
Would have been great to have Bart make a special appearance as the scientist
Well they also had Sr. Jerry the guy with a freaking mechanical engineering degree
The ignition bang trick works great on a carburetated motorcycle. Just flip that kill switch on/off as you decelerate in gear and youll sound like a drive by
Yeah I don't think it works vehicles with electronic fuel injection. To work it requires fuel to be flowing to the cylinders while the ignition is is off - so carbs and maybe mechanical fuel injection.
I was making my 1978 Datsun pop like that back in the 80's. Id rev to about 5 grand, cut the power for a second and turn it right back on. Sometimes id get a small flame out the pipes. Yes, it works
When liquid goes through my exhaust pipe I usually experience an explosion. Your results may vary.
Excuse me what?

Even though it did kinda work, in the first hack you can clearly see the guy scratch the rear passenger door (door panel gap between front and rear doors is on the right and rear wheel in picture) and after the cut the "fixed" panel is the front passenger door since you can see the reflection of the side mirror magically appear in the panel.

@@Telthar 100%
Known about the blowtorch trick since 2009, being in the Jeep community. I have done this with my own wrangler. It works. But like they said the correct plastic and the practice is what it takes.
6:03 Or! Hear me out here, you could realize that there is a reason that the opening to every oil bottle you've ever seen is on one side and not in the center. It's so that you can tip it, with the opening up top, and not spill oil everywhere. Literally every person I've ever seen put oil in their car, outside of people I've worked with in shops, does it wrong, and spills oil because of it.
Same with juice and milk bottles
I swear James has the cutest, most adorable giggle I've ever heard.

14:50 it only works on ABS, which is why it melted your mirror and handle, which are a softer plastic. The splitter will be made of ABS.
I won't lie, that exhaust pop "hack" is something I really do want to try once. I doubt my car will ever forgive me though
Won’t work unless you have a straight pipe 👀
Turn the quart of oil sideways when you start to pour and you don’t need a funnel.
The two small suculant plants on the desk really give off a "classy" vibe haha
small scratches tend to just fill back up with scooped paint when you rub them with towel or in that case tennis ball ....the scooped up paint (it doesnt vanish you scrath the paint off and it stays around the scratched channel) just returns into the groove you got on the laquer
After watching a lot of deep dive science chats its nice to kick back and see some idiots make slime for the 5th time ; )
You guys doing a lot of these types of videos lately, MORE! :D
I'm into 3d printing, ABS and PLA plastics
Sometimes I sand the surface and hit it with a heat gun afterwards. When you have a surface layer of sanded bits like that the surface will pool itself when heated giving that fresh clean new look.
There are chemical agents out there that do the same trick/hack/job. Not a scientist either, but love your vids. 👍🙏🤟
The torch thing does work I've done it on my dirt bike.. it's used to get the scratches and gouges smoothed back out. But you can mess it up quick if you have ocd... a heat gun works way better though
