Quote: the tanks wouldn't work because they wouldn't supply a steady volume of air. The pressure would be high at first, and as the tank got low the pressure would drop, changing what was happening at the paint gun.
Ever heard of a R-E-G-U-L-A-T-O-R ?? Its a strange little gizmo that goes on my welding tanks (one of which is oxygen) and maintains a CONSTANT output pressure. Come to think of it, scuba tanks have them and, dang, so does my compressor !!!!!
