Just don't choose a frame with fancy chrome headlugs for you first attempt or you may end up painting it twice like I did. The paint is automotive urethane.
I have to disagree about Dupli Color. It's lacquer and lacquer paints are not very durable at all. An acrylic enamel would be better. Dupli Color wheel paints are acrylic enamel, but there are only three or four colors to choose from.
