6675 - Krylon Fusion for plastics tends to do a pretty decent job. I generally fine sand and clean the surface and apply a couple coats of adhesion promoter before painting. A matte or satin clear coat is also recommended, as a lack of clear coat allows the paint to deteriorate faster, especially in direct sunlight.
6678 I'm figuring if it's durable enough to go on rims it will take the every day wear and tear for i terror pieces since the guy that previously owned my sti painted the shifter trim and center console and it has wear and tear from me shifting and turning knobs lol.6677 - I've never plasti-dipped anything, so someone else will need to chime in.
