I also use the badger sandblaster to spray powder paint, as well as their very inexpensive external mix paint gun. Both work well. I use a hot air gun to heat the jig, dip it in a fluid bed for the base coat, back to the hot air gun to finish the melting of the base coat, and while it's still hot, spray with one or two colors of powder in the badger guns. Because the base coat is still melted, the powder sticks well, then back to the hot air gun to complete the melting. (I just spray over a garbage can, the countershading uses very little powder, I don't attempt to salvage it). This gives a nice blended countershading. I have several guns hooked up to an air distribution manifold so I can just grab the color I want to spray, then just heat cure and paint the eyes. Part of the trick with the sandblasters is to keep the air pressure low (about 20-25 psi), so the powder doesn't come out in a fog.
