what paint guns do you use?

Binks Mach one(don't make anymore)
Devilbiss with 2.2 tip (don't use anymore)
PowerMate 1.4 and 0.8 touchup cheap and works good
All four are HVLP. Used a SATA a few times. When spraying special effects with a 1.2 tip, you still need to cut back fluid flow. I really like the Binks, but the thing is a hog for air, something like 13.5 SCFM at 60lb air pressure. Would like to get a different air cap that would cut back on the SCFM with no loss of atomization. Oh, I am not an expert, just do a lot of spraying for my job. Spray out of paint sample I make.

3M makes a cup and bladder system for spraying. Very handy to use, when finished just toss the bladder in the trash,( figuratively speaking).
