I have had no cracks or any imperfections in a year and a half.īTW, did I mention that it looks like a yellow mirror?
#Prefpping plastic bumpr for primer free#
I had great luck using SEM Plastic Prep as well as Sand Free in the preparation of my PDC cover which I painted with a bright yellow PPG polurethane. This of course is just a quick overview if you go to any auto body supply store they can get you the tech sheets that will tell you in more depth the process of painting plastics and if done right the finish can last for a very long time. It should go as follows.ġ-scrub with plastic prep and a grey scothbrite, don't be afraid of getting carried away it will only help the paint stick.Ģ-"wash" the part with plastic prep( some system use 2 different types depending on what you are doing).ģ-Wipe part down with wax & grease removerĤ-this step may vary-some systems have a final wipe specifically for plastics.ĥ-seal the part with appropriate sealer WITH flex additive.Ħ-after proper flash time apply base coat ( or if using single stage apply until desired coverage and gloss)ħ-after flash time apply clear coat WITH flex additive. If you want to do it right first decide what paint system you are going to use ( Dupont, PPG, BASF, Sikkens, Autocolour, etc) Then get the "tech" Sheet for given system.
