I'm sending this before I go completely mad.
The photo shows one example (there are many more) of what I can only describe as fish-eye contamination while trying to paint my instrument panel. This is Eastwood epoxy primer, but I have seen it with Akzo also. I have tried different paint, different guns, different compressors different metal. The only thing that is common is the location (my garage), and the season(temp = mid 40s outside high 50s inside). I etched the metal and alodined it. Later scrubbed the bejesus out of it with Scotchbrite after stripping the paint for about the 3rd time. I'm sure any alodine conversion went out with the scrubbing. Then washed it with Dawn dish detergent and rinsed with enough water to flood Texas.
If this were a woodworking project, I would assume silicone contamination and coat with shellac before varnishing. So I used some rattle can of self-etching primer, and, surprise, no fish-eye. Great. Then I sprayed the epoxy primer over the rattle can primer and took this picture.
I'm in the 6th year of a 3 year project, have primed the entire interior, and have never seen this before. I have moisture traps at the compressor and at the gun. I have never used an oiler, and as I said, I have used 2 different compressors with 2 different hoses.
If anyone can help me solve this problem, I will be forever in your debt.
Thanks and regards.
