Hopefully I will be spraying some epoxy primer soon (before it gets too cold). The body is nearly stripped on my 69 firebird project, I have SPI epoxy primer, 55' of sloping copper line (with drain at end) running to a craftsman 150psi regulator and Devilbis dessicant dryer, then 25' of rubber hose to an eastwood regulator and Concourse gun. I have several tips to choose from and should be able to spray anything from primers, base, to clears. I don't have a clue how to set this gun up (I have read Barry's article several times). Any thoughts on tip size, air pressure at gun, fluid adjustment, etc.
