judging by the smell of most nail polishes, I would say Ethyl Acetate is the thinner you want....my girlfriend's nail polishes all reek of the stuff....not sure what it will do to your plastic ...... might be so hot you wont even need primer....give it a try (most nail polish remover are acetone free these days btw)
