Donn Yost did a dvd on how to do this, if you want to look into it, but I just played around with it till I got it to work. I thin the enamel paint 50% with common lacquer thinner you can buy at auto zone, and have a squirt bottle of lacquer thinner ready in case the tip of the airbrush clogs up. I just tried different air pressure setting with different paint supply settings which I can do because I have a double action brush and a needle valve where the hose hooks to the brush to control the air pressure. Its like shooting lacquer paint except that its glossy instead of dull on the model. Maybe some people can shoot lacquer and it comes out glossy, but I sure cant . Thanks for the reply , D.
