is this stuff any good? And will it work on interior plastic?

 

Yeah its pretty good, and yeah it will work on interior plastic. My friend painted the entire interior of his Precidia with that stuff, dash, door panels, etc, and it turned out pretty good.

If you want to test it, just try painting the backside of your glovebox, or something you wont ever see. If it doesnt come out how youd like, throw it in the trash. Its like, 4 bucks a can or something.
