SEM brand is about the best for plastic interior parts. The parts need to be cleaned/degreased, dried and then you need to use an adhesion promoter and then very fine light coats of the SEM top coat to achieve the desired results.

So far after 2 years, I've only found one small area where it has chipped or scratched... but at least the color on mine was almost the same underneath, so it's not obvious.

SEM usually can be found at most automotive Paint supply stores or on line and they have the widest variety available.
