Paint Dries Fuzzy

Thanks Nathan and Don.  It was the trifecta of not thinning the paint enough, too much distance, and not remembering how I used to do things.  

Roughness can be caused by at least three things- too thick a paint, too much distance, or too high a pressure.  Or, of course, it could be any combination of them.  I do notice a tendency to use an airbrush like a spray gun. In an attempt to speed up painting and cover too great an area at one time, we tend to back off the distance and that definitely will roughen the finish.  Consider the airbrush as more of a brushmark-less brush and less like a spray gun.

Thin it with Mr. Color leveling thinner, at a ration of 1 part paint to 1.5 parts thinner. This stuff will go on rough if your thinning ratios are too thick. Not very forgiving stuff in that area.

I think I have it figured out.  I believe it was a combination of not being thing enough, and spraying too far away.  The Airbrush Guide helped me out.  Also made me realize I was using fuzzy, when I should have been using gritty, to describe the problem.
