I'm going to be doing a LOT of finishing using General Finish WB, and my old wrists just can't run a brush for very long. I have a Dewalt 5 gal, 5.1 CFM compressor, and not really in the market for a bigger (more expensive) one. Any good recommendations for a gravity fed spray gun that will work "well" at 5 CFM? I'm "ok" with letting the compressor "catch up" every few minutes. I'm not shooting for museum quality furniture finish, just high quantity without obnoxious orange peeling. Thanks!
