I'm in an art class where we are encouraged to experiment!. I have an old metal "No Parking" sign that I was thinking of using as a canvas!. The letters are raised, and I think it would look cool to paint a portrait or something over it!. The metal is probably similar to a license plate, but thicker!. The sign is already painted, and it's in good shape!.!.!. No rust or anything!. I just don't know if I need to strip the original paint first or prime it with something or what!. I also don't know what type of paint I'll need to use -- right now I've just got a lot of acrylic paint, but I have a feeling that acrylic paint would peel off once dry!. I could go buy some more materials if I need to!. Anyone done something like this before!?Www@QuestionHome@Com
