I agree. Sanding is the MAJOR key to painting plastic parts. I went to Pepboys and used Vinyl paint for almost everything else. Then I bought some red vinyl material for like 3 bucks a yard and did the panels. The vinyl paint sticks really good since it bonds well to the vinyl of the doors, dash, etc. I did put a good amount of clear coat on the plastic parts after I painted, since I didn't do it the first time. I learned the hard way on how to properly paint plastic parts.
