Full Version: How do you paint plastic?
Does anyone know how to paint the plastic on quads?
clean the crap outta the plastics with a very, very fine scotch brite (super fine - you can get from an auto paint dealer) and comet
sand again with silicone/wax degreaser... the key words here are clean and adhesion. Now, I don't know what adhesion promoters are out there right now cuz I've been outta the game a while, but then you'd probably spray a coat on and some primer on top. spray with black paint (mist coat to work as a sanding "guide coat") then let dry over night. sand the primer (4 coats) WITHOUT BREAKING THROUGH!!! If you break through you must reprime those bare spots. Now, if you think your plastics will flex, you must add flex additive...
You're going to wet sand the plastics after they've been primered with 500 grit wet paper. On the edges of the plastic do not use the sandpaper, use the finest scotch brite you can find, so you don't break through the primer on the edges. Also, remember that the primer you will use will be "catalyzed', meaning that you have to mix hardener into it. Don't use cheapie stuff here....
One you have "final" sanded the plastics and there is no "guide coat" left... you're ready to mix and spray...
I hope this helps... I just rambled on off the top of my head right now, but you know where I live, so maybe we can hook this up one of these days in my garage, where I've painted at least half a dozen cars before...

I painted my plastics on my quad with the new krylon fusion paint special for plastics, just a couple coats and there great.

The problem with painting Quad plastics is that the paint must be flexible to with stand the vibration and bending the plastic goes through when riding. Even thou the Krylon Fusion paint may adhere to the plastic will it hold up under stress without cracking or chipping. In the past I used to paint parts on my Quad and after just about every trip I would have to go back and touch those areas up because of chipping and cracking. If you have old plastic just look at the small hair line stress cracks that are in the plastic, white plastic show these stress cracks better then any other color because the dirt that gets into them. These are areas that if you paint with standard none flex paint will start to crack.
Oh and I was told that even when using flexible paints on the rear plastic it's still a good idea to brace up the rear fender to minimize the flexing of it...Even thou you are using flexible paint It's still paint and with all paints bend it enough and it will crack.

the flex additive comes into play only in the primer and in the clear-coat, unless you're using single stage paint, which does not require clear. I recommend clear coating it because then you can "blend" in any repairs later.
Be prepared for lotsa work. I hated using flex additive in primer because it makes the primer gummy and hard to sand, but that's the case with the good stuff.
You wanna do this once and do it right, because if not, it's going to be headaches after this from here on out. Plastic is the absolute WORST thing to paint (correctly). Anyone can spray a nice paint job, but it's the prep that kicks your a$$....

oh yeah.... when you sand the plastics themselves... make sure there are NO shiny spots...
shiny spots = NO ADHESION
paint needs the scuffs to "bite" into

just dip them in Plasticote
Done deal.
Done deal.

they are most likely a owner modification. i made some brakets to support the fenders on my predator so i could take the heel gaurds off.

probably a grind wheel and a couple of weld should do the trick right?
