I'd seen the thumbnails for a few of these CA/Baking soda videos but yours caught my eye because it mentioned plastic gas tank. I've been dealing with a leaking gas tank on an old Murray lawn tractor for over 3 years trying to seal the cracks (plural) and even tried "welding" it with a soldering iron and polyethylene scraps from old jugs. But the cracks kept spreading. Watched your video and figured "I've got several little tubes of dollar store CA and a 25 lb bag of baking soda so why not?". Roughed up the area with files, sandpaper and a stainless steel wire brush. Also drilled holes at the visible ends of the cracks to hopefully stop them spreading. Biggest crack is/was 1/8" wide and 1½" long. The result looks good. I tried to pick off a "run" that had soda on it and it doesn't come off! I've put the tank back on the tractor but discovered there's water in the fuel filter (frozen) so I can't test it till spring. I'll try and update this when I do fill the tank and put a few days hard use on the tractor to see if vibration causes any trouble. i.imgur.com/giYfHqj.jpg i.imgur.com/PKc7THe.jpg
I've used super glue to seal the cork floats in antique carburetors so they don't absorb fuel, also the cork floats used for fuel level sender assemblies. Works well and doesn't dissolve away..
Bob, I have used super glue and cotton string to fix even the transmission cooler tube where it leaked on the line that went into the cooler on my Dodge 3500 Ram two years ago- still holding. Hit on this idea ten years ago when my fifty dollar Chinese built to break headphones separated, I have them on now as I listen to your great video. Works with cotton thread also have used cotton jean material as patches to build up broken parts. Why don't you make some more videos using this idea so more people will learn of it...
Bob, I looked for a followup video on this and I don't think you posted one. Did you find that the cut you made with a razor knife filled completely with no seepage and is this method for sealing gas tanks resistant to fuel?
Seems like an easier test would be to take several small glue-ups and put them in a jar of gas for a week. That way you're not potentially ruining a perfectly good part.
Don't know if a crack reacts the same in plastic as in steel but I would also drill a small hole at the end of the crack. in steel a crack will run you always drill a little hole a little past what you see as a crack on both ends..A good video Thanks...
Rick F, yes, I agree with your advice to drill a small hole at each end of the crack. I work on audio equipment and I do the same when repairing cracked printed-circuit boards. Otherwise, the crack just keeps on spreading.
Yes,but *NOT* here; if the glue fails,you'll have a flood instead of a small leak; AND this is not a structural crack,it is NOT going to progress,he did it with the knife,the crack will always stay put.
Thanks for this, I just used it to fix the bottom of a plastic vase and it's working well so far! Have you tried any other powders... I've heard of people using talcum/baby powder and even fine salt or sugar but never tried them! It'd be a cool comparison video if you decide to do a follow-up! Thanks and God Bless!
"That tasted like shit!" lol, It's good to see that I'm not the only one that does that kinda dumb sht! Thanks for the tip, Bob, I will definitely be using it!
I was thinking if you felled the tank wth bakingsoda and poured the glue into the cracks it would act as a good internal base and then fill from outside...
Hi there Bob, hope all is well. I am now facing this issue and baking soda super glue trick. is got to admit neat thing in your tool box. Guitar players fix their Nutz with it I have used to rebuild a pair of glasses but I wasn't sure if it was gas soluble? but looking at comments section., Seems like it is . But Myself I get technical maybe too much but you can't overlook one factor: What type plastic are you adhere ing it to. My tank is the HDPE 2 and I got a crack almost two inched long. crossing fingers I am glad you reminded me about this trick thanks
Wow thank you, you just saved me 15 pound,I wish I had seen it before I bought the first plastic tank repair kit, then that could of been 30 still you've saved me for ever now ha thanks again I subed for your knowledge and skills.
In South Africa we have had a product that came out 15 years ago called Q bond works well grey powder and black powder Am a panel beater and use it often,to temperately hold bumpers prior to fiber glassing the split
He's using regular super glue? I bought vent caps to retro fit into a new gov't can. I used a step bit and made the mistake of drilling into a spot that was molded thicker than I expected. Thickness caused me to drill the hole slightly too large to hold the vent. I'm sure it could be fixed & done right with the right glue. I wonder if this will work. It's snug but not tight enough. I'll have to try this to save a can. DAMN GOV'T!
In my experience, JB Weld is solvent-safe, okay for use with gasoline anyway. Be sure to clean and rough up the plastic so that the glue has some "tooth" to grap onto; and degrease it thoroughly before gluing.
If you can empty the tank first then this looks good. However, you can't always do that. I stopped leaks in a car gas tank (metal tank) by using Seal All. My gas tank was leaking steadily (drip - drip - drip). I applied the Seal All and over a minute or so it solidified and no leaks. Lasted for a year until I went and washed the car and used the spray want on the tank area I had repaired - the pressure washer managed to spray off the seal all. But, all I did was to clean up the area and apply seal all again!
If you are doing a lot of CA gluing you would be doing yourself a favor if you use a rubber respirator. A good 3M one , not a cheezy paper one. The fumes go into your nose and the moisture kicks it. After a while your nose will be burning inside. It's fairly excruciating. Or use a suction fume extractor.
Nice video. I've used the super glue/baking soda combination for alot of repairs mainly O-ring seals. Interesting to see if it will withstand gas and other harsh chemicals. A good video idea would be to place the glue/baking soda into the bottom of a see through cup and add a variety of different liquids such as gas/diesel/kerosene etc. just to see how well it holds up.
Why would you chance ruining you bag of baking soda by pouring the old back in the bag. By the way, I've been using "CLEAR GORILLA GLUE" for projects & repairs like this. It's fantastic. I even used it to glue the rear view mirror mount to my truck's windshield. It has held for over 6 months after the glue I bought to glue the mirror mount did not work & mirror fell off.
What happened three days after the cyanocrilate and the soda did not dissolve? What was the result I need to repair a plastic gasoline tank and I want to know if the cyanoacrylate does not dissolve in permanent contact with gasoline, I would appreciate your support
I experiment quite often. I've gotten pretty good at plastic WELDING, but there have been a few cases where things got a little tight. H2O you say? I'll get back to you on this ... I love to do stuff that people say can't be done. Most of the time people say it won't work boils down to the simple fact; THEY DIDN'T TAKE THE TIME FOR PREP. Hell, anybody with kids or a sweet tooth can tell you how hard it is to get that shit off the bowl, and this is without ANY prep work. I'LL BE IN TOUCH
@@vrossi2596 I am so sorry, I haven't had the time to experiment. One thing I can tell you, I go for the Loc-Tite brand superglue in the light blue bottle and the baking soda. Yes, I DO want to try the mist of water, but I haven't the need as of yet. And the main thing is, it's all about how one prepares the surface of the material. Make sure whatever adhesive you are using has something to ADHERE or GRIP to. If you do this, you should be back on the road in NO TIME. And I WILL get back to you when I test the misting of H20 on the SG. PEACE
I am interested in this subject matter. Would you take a new tank and pressure it and see at what pressure the tank busts??? Then take another tank that is the same and damage it with the drill and cut method and pressurize the tank and see how much pressure it will take before it fails. Then you will know at what pressure the tank will fail and the percentage of the real repair strength which is really important since you are holding a flammable liquid for safety reasons. Hope you do the test Sir. Peace and stay virus free too. VF
I had the loctite gel superglue with baking soda and it failed to stick to polypropylene. Cheap thin superglue from the pound store worked much better, but it seems to work like a sticky patch bigger repairs are more durable.
Plea see let me know if it works I busted my auger gas tank and it has a crack now I had a mechanic tee y to fix it he put epoxy but didn't work so I would live to tell him how I fixed it lol
Skyler Gunnels I have the same question. I have a plastic gas tank that has a larger hole, and I can't reach inside to get behind the hole. May I can pack the tank with sand to have something behind the hole?
It work fro me on my xr650r tank but I use the soldering iron to close the cracks first, sand paper the area and then apply the soda first and glue slowly.
I much prefer this method over melting the plastic with a soldering iron. Thanks Bob!

I gave it try works awesome thanks ! I bought a kit from amazon that said stop leak for plastic tanks fail big time .
Glad it helped, thanks

Very good tip! Also, thanks to Rick F. for the drill hole, at end of crack tip. Thanks for posting!
im going to give this a try, thanks for making the video, I think i'll skip the taste test though
thanks
cool
Did it work? I couldn't see a follow up video about the gas if it leaked out or not.
I too was interested in a follow up vid
Yup it did work. It’s on his video list. Give them a watch to help his channel 👍

Yes,but *NOT* here; if the glue fails,you'll have a flood instead of a small leak; AND this is not a structural crack,it is NOT going to progress,he did it with the knife,the crack will always stay put.
Sure,but *NOT HERE* the crack ain't going anywhere,it is not a structural crack,and,if the glue fails,you'd have a flood.

thank you sir
Ist heat resistant?
Do you think you could drill a hole in a plastic tank on lawn equipment and retrofit a different size gas neck fitting for the gas line to attach to?
Will the super glue and baking soda work on a car gas tank underneath the car .....
I repaired my rad on my Dodge Ram with crazy glue and cow brand and it was awesome how good it worked and lasted
What was the outcome?
would this work on a cracked bathtub
Hi
talking about the glue, crazy glue is consider super glue? may I work with crazy glue and baking soda with the same results? thanks
SAME THING, BRO...
When the garage lights up you can use the baking soda to put out the fire!!
So did it hold?
What was the result Bwana Bob? Did it hold up? Did it leak through?
In South Africa we have had a product that came out 15 years ago called Q bond works well grey powder and black powder Am a panel beater and use it often,to temperately hold bumpers prior to fiber glassing the split
Any tips of sorting out a gas tank im also from south Africa

It will hold a 8 inch crack in a radiator without leaking pressure should hold almost anything together i say

Cool looking forward to the results. 👍:) I hope it holds. :)
thank you, so far so good holding up.
Awesome , welded up a hole in gas tank, and then tried this over it. Cause it would seem out...thanks for the idea....
Seeped
works great.
just make sure you ruff it up very well thats what makes it stay on, good luck. thanks

Thanks Bob, putting this in the trail repair kit.
My snowblower’s gas tank (plastic) was chowed through by rats and leaving big hole on it. Ant idea of how can I fix it please?
same here still trying ideas 1 year old mower 600 bucks and a new plastic tank is $ 200. not happening
What a Idea sir ji very interested your work I used in India.
get a clean peace of card board then look( other was wet)
Magic
I've tried it on wood before but like you said it soaks in too quickly... I tried it with gel super glue though and that actually worked OK!
I had the loctite gel superglue with baking soda and it failed to stick to polypropylene. Cheap thin superglue from the pound store worked much better, but it seems to work like a sticky patch bigger repairs are more durable.
Try soap to stop a gas leak.
Great I will let you know my results
me to, thanks
Would that work with diesel ? On a tank
Still holding?
so cool, let me no when you hit like 3 month. thank you bob
Plea see let me know if it works I busted my auger gas tank and it has a crack now I had a mechanic tee y to fix it he put epoxy but didn't work so I would live to tell him how I fixed it lol
i did it 5-6 weeks ago, and its still holding. clean it up on a wire wheel on grinder wheel very good, that's the key. thanks
When your done can you get screw driver and see if patch comes off
What about larger holes?
Skyler Gunnels I have the same question. I have a plastic gas tank that has a larger hole, and I can't reach inside to get behind the hole. May I can pack the tank with sand to have something behind the hole?
I'm thinking maybe pushing some gasket maker into the whole might be good to fill the whole and put the super glue and baking soda on top of that?
Push some tape through the hole and work it to cover most of the hole and then go from there?
Check out the channel called Sweet Project Cars... he has several videos on repairing plastic using both super glue and epoxy and fiberglass!
How long do you let it cure out??
10 min
5 or ten minutes. thank you
Can l use to stop cracking radiator(plastic)?
CA and graphite.
OK Einstein ,You can use my pressure tester..
Should have put the hole under neath the tank
Did it leak?
still holding, thanks
Did you try stitching it back together with a soldering iron? Welding it? It works great.
Am i the only one who thinks that's a colossal waste of cocaine?
Whazaaaaa
It work fro me on my xr650r tank but I use the soldering iron to close the cracks first, sand paper the area and then apply the soda first and glue slowly.
cool
What the hell you ruin a good tank,, All you need to do is mix the glue and soda and place into a bowl of gasoline to see if it dissolves
Repaired my mower s float busy soaking in juice now to check if it dissolves.
"reduplicate?"
Moises Hernandez lol
Baking soda joint swells
did not swell when i did it. held for weeks ok.
Follow up video?
This guy says you put the baking soda in the crack 😂 man you can't have crack without baking soda
"bacon soda?"
Emory croft
I can't get past what chocolate dipped bacon tasted like.... Bacon Soda would be worse! ;)
How do you know what shit tastes like?
Yosemite Sam would have used a match to check how much gas was in that tank.
