Enzie, The paint that I work with is an air brush ink. It thins with water for airbrushing to whatever consistency you want. It has an acrylic base so probably couldn't be combined with oil paints. If you used acrylic or water soluble oil paint it should work. I get it at
Dharma Trading in California. Check out their website, it's a lot of fun. It's also not as toxic as what you're trying. Good luck!
