Hahaha as it happens seventeen inch wheel fits in my dishwasher. Loll
Seriously, they do 🛵
i kept trying to think how he did that lol
@@karadanvers6136 actually how can you convince the wife that you wana put the wheel in dish washer,,,
Just because you whistled, I’m giving you a like 😂
Love how you say, wait till the wife is out! Haha. I have found many car parts in the dishwasher lol
I spent so long in watching tonnes of videos, but non came close to your actual presentation and how to do this properly, appreciate it a lot, cheers!
Yup 100% agree
in all my years i have never seen, or heard of, a propane gas torch for this purpose/effect. I have painted many rubberised plastic car mouldings and have not had a problem with adhesion. I usually clean well (cloudy ammonia added to the wash bucket removes all silicones and waxes) then lightly scotch, then quickly and lightly washwipe with paint thinners rather than Wax/Grease remover, allow to thoroughly dry, tack rag then plastic primer. I use a clear plastic primer that is probably more like an adhesion promoter such as PPG Deltron D820.
Not saying the torch method is not effective, i've just never seen it. Probably worth mentioning the torch method is only for 'raw' mouldings and not painted ones..obviously
Trying this again on my plastic phone case (made of PC hard-shell) because they don't make the color I want. Tried it the first time with my old case and it appeared that the matte spray paint (which says it is supposed to work on plastic and has a primer in it) stuck well. I sanded prior and cleaned. However, a week later, I tried to clean my phone case with a clorox wipe and the wipe was wiping off some of the paint. Not peeling it, just smearing it off. I have to be able to clean my phone case with these wipes.. clearly a chemical rection is happening. Any thoughts on how to keep that chemical reaction from occurring when using wipes? This reaction does not happen when I use the wipe on the original cases paint job. Do you think this happened because I used a matte finish? Do you think satin would would better? I saw that you used a blow torch for PC... I don't have that. Is there another way? thanks
Im thinking of actually buying a second hand parts washer now for the wife,
😂🤣😂🤣👍👍
Fantastic video, very helpful indeed. I just hope your wife doesn't see this video and you have to explain all the stuff you've washed in the dishwasher..
Thanks Natasja.
Using the dishwasher is risky , wifey gets angry and i sleep outside the house
Oooh, yes. Cover your tracks well.
Tku new subscriber 👍💞
I'm wishing to paint my bumpers
My self yu see" can yu paint with out taking them off? That's a bit hard for me actually 😕
One small thing to note: using a heat gun to pretreat the parts will NOT work. Its the actual flame oxidizing the top layer of plastic. A great way to test that your flame treatment was successful is to drop a few drops of water on the surface. If it sheets when spread on the surface your good to go, if it beads, treat more.
great video overall, lots of helpful lil bits!
Thanks Buddy, i never new there was plastic primer waao, ive a blue chainsaw & orange forestry head gear, Now i know how to prepare the orange forestry helmet to be sprayed blue, the same as my chainsaw. Cheers 👍💯
I sanded my front plastic dash piece with 220 grit then 320 grit and then wiped it down with wax and grease remover , then I painted it what I thought was going to be flat dark charcoal grey is what the paint cans cap color was , it turned out shiny black and it feels rough when I run my hand across it , I think I made the plastic rough when I sanded it , I'm very disappointed
Excellent video mate, very thorough, well explained. 👍👍
Thanks for that information, it is very helpful. I am getting ready to re-paint some interior parts after I screwed them up with improper prep. Have a good one!!
How did it go?
My wheels in my dishwasher ten minutes after watching this
Great video! I appreciate all the tips very well explained and love your demeanor. Keep up the good work
Thank you Eric
Do you sand the primer at all?
Ok I got everything, except what kind of paint is best for plastics?
Any paint you like, as long as the primer is a plastic specific. It's the primer that provides the adhesion to the substrate - ruclips.net/video/BVTASVSPezQ/видео.html
Nice and simple and well presented. Thanks :)
Thanks
Hi there, great vid! I want to paint my mirrors caps which have a chrome finish at the moment. They're plastic, was wondering if I need to use an etch primer first, and how many coats do you recommend for primer, paint, and lacquer? Is two enough. 👍
How to proceed depends on whether they really are chrome plated or aluminium like headlight reflectors. If it really is chrome, you won't touch it with w&d paper. You will need to strip the chrome off first. ruclips.net/video/CDF3A3xUYeY/видео.html. If aluminium, start with 600 grit w&d then 1200 grit and yes use an etch primer first. If you go through the aluminium to the plastic in patches, then take all the aluminium off and start with plastic primer. Alternatively, get the aluminium off by putting them in the dishwasher for a couple of washes.
@@CycloneCyd thank you, I'll see how I get on. I'm pretty sure it'll be plastic as they're Mini mirror caps and the caps are a rather thin plastic but I'll definitely check. And how about the number of coats, is it a 2 to 3 or do you keep going until happy with the look of the finish?
About 3 months ago I bought my first Saab an silver 07 Arc I tried using transmission fluid and a heat gun method on the door trim to restore it. It looked good for a couple of days then faded worse so I cleaned them with alcohol, taped off with newspaper, used plastic primer and then trim restore paint. So far so good but we'll see if it lasts. Thanks for the video I didn't think about taking them off the car.
I'd be surprised if it lasts long after having put MTF on them and heated it. the surface will be contaminated. You never know your luck though.

@@CycloneCyd I used new ATF and I didn't paint it the same day, about two weeks later. The black parts on mirror absorbed the ATF and look brand new but the door strips being softer didn't. Anyway thanks for replying and for the video.
Thank you.. You are a great teacher 👍👍
Love the bit about the wife being out, smart guy you are!
Ha ha, I know which side my bread's buttered!
I'm looking to paint the black trim on my 9-3 to color match ut, I have backup sensors though, I have read conflicting posts on if you can or can't paint them, did yours?
OK, I can clear up the conflict for you as I used to deal with Plastic Omnium testing warranty returned sensors for JLR: *DO NOT PAINT THEM*
Fantastic. Your wife was probably wondering how the lug nuts got into a dishwasher? I'll be painting 1991 mitsubishi 3000GT. How do I know if all that plastic is hard or soft? Is there actual test? Also your part is new. If I'm just sanding off the clear, so do I still prime it?
Nevermind. You just answered it for Malcolm Ward. Thanks anyway.
Oh, I did? Great, glad to help
I'd be far more interested in learning how to paint (spray can paint) already painted plastic parts on my car. Mirror covers as it happens.
My amateurish logic tells me, just sand the original paint/clear coat gently, without cutting through to the plastic. And go from there with primer, base coat and clear coat, in multiple layers probably.
But I'd like a professional opinion!
If they are already painted, sand with 600 grit. No need for primer unless you have plastic patches showing anywhere, in which case use plastic primer.
@@CycloneCyd thanks very much!
Hi
Thanks for vid, yr an easy bloke to listen to.
Firstly...."as it happens 17inch alloys fir in a bishwasher" 😂 hope the wife doesnt watch this lol
But it just seemed yr vid ended a bit quick.
You said "bake at 60 for an hour" i am painting interior parts on my mg zr which wont fit in oven, how do i bake them?
Also, how many layers is best?
Should i be applying a finish lacquer?
Im wanting to freshen the interior up and change the horrible cream coulour to black, also want to add some green accents....do i paint it all black and do the green on top or mask off each section seperate?
And lastly, will this work for the sun visors.....they are a very soft plastic cover....wondering if constant sun is going to affect anything.
Anyhoo, sorry for the barage of questions
I need to get a new piece of felt for the roof liner....thinking of a starry sky type patern, and really want to put some effort and time into doing the interior well.
Thanks again for the video and help, ive made a list and will be off to get prep items and paint soon 👍
2:30 ...and if the wife's out ...
Painting pp pe plastics are not always easy.I dont heat them up just clean it good then apply plastic primer then primer and colour and finish it with 2k coat.I heard also the best to use flexible paint or primer because paint can crack on these soft plastics.
Great informative video bud, with the soft plastics do you prep prior to heating the part or warm first then prep ? …. Cheers 👍
Run the flame over it first. the purpose isn't to warm the plastic but to create a chemical reaction on the surface that helps paint adhesion
Well done 👍 & liked.. I have an old laptop plastic back case to spray paint black which is originally black .. and it's a lil dusty.. For pre cleaning, should I wipe it down with isopropyl alcohol or just plain warm water with mild detergent before spraying paint.. what do you suggest?
Also is a primer spray mandatory which I don't have at hand?
did you actually watch the video vira
I’m gonna paint a pair of sunglasses frames that are already painted, how should I do it? You told another guy to skip the primer and use 600 grit
Very informational good job too
👨🏫👨🏫👍🍷
You forgot to mention if the part was primed already or no. There's a big difference when the part doesn't come primed
Where did you get the scotchbritw pads from mate, I just want to make sure I get the correct a abrasion. I'm going to me painting a rear aygo bumper. Thanks
What a lovely guy 👍 and helpful as well. Everyday is a learning day.
very thorough explanation on doing the cleaning and spay painting of car parts that are being spray painted, thank you Cyclone Cyd from Edward Scott in Queensland, Australia.
like for Saab
Any suggestions for plastic paint strippers? I have to remove the paint on my motorcycle fairings to repaint them.
How do you paint a plastic part that has already been painted a different colour?
provided the existing paint is sound, just give it a light sand with 600 w&d, clean and paint.
Hi Cyd - thanks. That is what I thought. Might put some adhesion promoter on as well
@@malcolmward yeah, plastic primer is also called adhesion promoter. Use that first.
Does the heated plastic part have to be still warm while painting?
needs plastic adhesion spray
That's a valid option, but plastic primer does the same job.
will this job last for multiple car washes a month?
TOPCAOT AFTER 2 HOURS?????? PLEASE EXTEND TO THE START OF THE NEXT STEP
very knowlegeable video. thanks.
This is verry funny shukup ahu
🎸 😂
Would this process work to paint a plastic kayak?
Absolutely brilliant, thank you Mr Cyd
99% prep and 1% painting.
Yep, about that.
Excellent tutorial 👏👍
Thanks.
Thank you
And to you too
Thanks again
Thank you too
Thanks I enjoyed that keep going it was great
Cool.
Great Tutorial
How important is the baking? I wish to paint a large item that won't fit in the oven
Some plastic paints do not cure aircure. You need bake them, fe 180F 30min. Maybe couple of heat sources?
Check paint PDS,TDS.
Nice
Great vid big bro very helpful
Loved the video thank you!
Thanks
Great work
Thank you! Cheers!
i liked this video but you forgot to put a close up of the final finish :(
Ah, there's a reason for that. This video is about *preparing* plastic for painting, rather than the painting itself. I see so many people just dive straight in with a bit of w&d, ordinary primer and paint and then wonder why it's all coming off a few months later.
@@CycloneCyd still would be nice to see a completed shot that lasts longer than 1 sec.
Haha if it fit in the oven bake it!
That's exactly what I do 👍💡
How far after the primer, is it proper to put on the first coat of paint?
Great video!!!
I just wait till the next day, but I'm not racing against the clock as a pro does.
The clear coat is coming off plastic parts on my 2007 Honda Pilot. I'm going to paint them installed. I'm real good at masking. Real bad at taking things apart. Thanks for the information.
Thanks for your comments Padwan, much appreciated.
Great advice, thank you for taking the time to add this. My job, repainting Boxster 987 centre console to get rid of the horrible sticky rubber coating thats chipped and sticky.
Oh yeah. those 'soft touch' paints are great when new, but just don't last.
Thanks for this video. Plz make video on How to paint 6 inch PVC pipes.
Hey this was real sweet
