Im needing to paint all my plastics. I know the plastics are black anyways. But im wanting to do a white, or just something other than black. Some of the plastics are scratched up and have scuffs on them.. Should I sand it with a fine grade sanding paper before painting? | ||

Do not epoxy prime!! I called ppg up and asked them about painting plastic.I have painted for years now and have gone through trial and errors. Wet sand at 400 really good.PPG sells a water based flexible primer.Before using the primer ppg offer a prep kit.I strongly suggest this.Its not just a alcohol wipe sponger either.It has some kind of nanotechnology chemical that penetrate the plastic and seals the pores of the plastic.That way when you add chemicals down on the plastic "YOUR PAINT" it will adhere better and not mix the oils with your paint.Therefore getting better adhesion.Now onto clear.Use the ppg omni clear.Its cheap and works great.Along with this use the flex additive in the clear to keep your the clear flexible.It says add 10% I add up t0 20%.I was told that the reason for 10% is because anymore will slightly changes the tone of the clear.But if the whole bike is plastic unlike a car I would go 20%.If you go to a ppg shop and they dont know what you are talking about go to another one that does.I made that mistake before.I bumped my car into a workbench and the paint just spidercracked.The primer didnt even stick to the plastic.The adhesion was bad.I did a test piece with the setup I spoke about and smacked the plastic piece with a deadblow hammer no cracks.Needless to say it took 2 times but now I know the right procedures.  | ||

Blackflash; My riding buddy owns a body shop and in the last 30 years I have heard pretty much the exact advice given many times. His business has regular body shop work and there are usually a few 'time and materials' projects in progress. Those are show cars. I like your writing style, could explain the term 'gassing out'. I have heard it discussed, can you refresh me on this subject. as I understand it timing is everything. Letting your primer sealer age/'gas out' before painting is.... dannybuell |
