I have a little one gallon that works great. Under desk, fairly quiet, but does not have a moisture trap.
Occasionally, my gun will "spit" extra paint. Could this be the problem?
And a hot tip, don't need to follow it if you want to live life on the edge, but always turn the compressor off before calling it a night. Nothing like having that little motor automatically fire up about 10 minutes after you crash. (No hobby room. Bedroom is the computer/hobby/sleeping quarters).
