I'd like to paint some of my interior parts silver, to go with the rest of the car..especially the speaker grilles, the passenger side has some purple nail polish where the previous owner's girlfriend must have spilled it. There was some on the passenger side dash (a good table I guess) but I managed to get that off. I want to attempt it when I install a system, but, I don't want to find out after the fact that priming/painting the grilles will clog up all the little holes and so look retarded....
