there's no guarantees obviously but good on you for trying. i think i painted the above machine's plastics because t wasnt aware of retrobrite yet but i'm not sure. even if i knew about it i probably still would have painted for a couple of reasons. first is there were at least 9 pieces and i wanted them to all be the same original color and with retobrite thats not always going to happen. also, the ashtray was damaged from cigarettes so i had to grind out those areas and fill in with plastic filler and that can only be hidden with paint.
