You can also use acrylics from the craft sections of hobby shops as well as department stores like Wal-Mart, they are cheap, come in a wide range of colors, can be thinned for airbrushing and come in metallics, glossy, flat, etc. Most of my paints are craft acrylics made by Folk Art, the only thing I dont like about them is they are kind of a soft paint compared to others.
