I rinsed everything with acetone then sprayed a cup of acetone through it. Hopefully I won't see any fisheye when it comes paint time.

Glad you found the oil and purged it. Generally if you put a charge of lacquer thinner in the gun and shoot it through it should clean out the critical areas, but with anything made in China or the Pacific Rim and shipped in you may have some pretty heavy preservatives, like cosmoline.

I'm still not sure what caused my problems, but I bought a new gun today and it shot primer great. In defense of the Harbor freight gun, I did buy a gun mounted regulator with this new gun, and I had not been running one before so I really have no idea what my pressure was at the gun with the drop through a 50' hose. As I was headed out to the shop this morning I did notice this on the counter that seemed to be appropriate to my problems. I don't think we'll buy any more of this stuff, just in case .....

That certainly could have contributed to the problems in oh so many ways.

Roger - I think we MIGHT have believed that statement had the cork not been so conveniently pictured. I'm with Steve > Now about the Fish Eye(s)...........

That bottle is unopened
Seriously, I picked up a Finex (by Sharpe) FX3000 gun yesterday (could not justify Sata or Iwata cost) and shot a bunch of cast pieces (brake calipers, caliper mounts, bolt heads and nuts, etc) and axle flanges that I had overlooked - a coat of epoxy primer, a coat of base single stage black and a coat of 50/50 black and clear. Before priming I soaked everything liberally with lacquer thinner from a spray bottle, wiped dry and blew with air. The new gun worked great with a definite difference in atomization. Since these were not "critical" parts I just hung them outside on a 2x4 supported by ladders so I was not in the same environment - did not want to take time to segregate the shop, and not overly concerned with a bit of dust or a bug or two. Also, I put a gun mounted regulator on the new gun, to be sure of the actual pressure at the gun - I may have been losing 5 or 10psi before and not realized it. One of these days I will mount the regulator on the HF "Pro" gun, mix up some primer and try it again on a test panel to see if that was the problem. For now, it is assembly time!!

I'd prefer a nice Port!

That is good news Roger! Glad that you're ready for assembly, (read that as jealous)...
