This is my first try with my Devilbiss JG-503 paint gun. I've painted with HVLP guns and know that the pressure to the gun needs to be within a certain spec. On a regular gun such as the JG-503, what pressure do I set my compressor at? Also, what is the difference between setting the paint cup to drip free or conventional suction. Any help would be much appreciated.
Thanks,
Don
