I don't use a lot of it, but I have used it some. It's basically just a clear carrier with a little bit of pigment, so I treat it just like any other acrylic paint. I thin it about the same, and spray at the same pressure and distance from the model. Using my Omni airbrushes, I usually thin it about 3:1, spray at about 12-15 psi, about 4"-6" from the model.
