Howdy, I've got a few repaint jobs coming up for which I feel an airbrush would be the only way to go. That said, who here uses an airbrush? What kind? Single/double action? I've seen the inexpensive units in Walmart, etc., but am really skeptical as to the quality and control afforded by those products. Anyone here tried one of those? I don't want to spend a buttload of $$ on one, but I don't want to end up with something that will let me down either. Thoughts? Recommendations? Thanks!
