Acrylic craft paints are pretty popular. You can get them at any craft store and Wallmart carries them, too. On sale they'll run you about $.50 a bottle and a good craft store will have more colors than you'll know what to do with.

Just as a caveat, I crest in a different manner so I haven't used these. But they are supposed to be compatible with gasket lacquer.

Testor's model paint has its affecianados, too.
