2 major airbrushing problems

If your dad's airbrush is a metal Badger (not one of the plastic ones) disassemble it, and soak everything EXCEPT THE AIR VALVE in laquer thinner overnight.  Get some pipe cleaners or "Interdental Brushes" (any drug store in the area where the tooth brushes and toothpaste is.  They are tiny little brushes for cleaning between your teeth).  Scrub it out good and then blow it out with compressed air.  It most likely has some dried paint in the nozzle or in the air passages in the head or body.

As to the fish eyes, it was probably moisture.  Those cans get so cold and the "Air" from them is so cold that they can make their own moisture when it hits warmer air.  Could also have been some oil or mold release as was already pointed out.

I should've mentioned the '17 had a white primer coat that the chromate went on over. It went on beautifully on the right, but not on the left. I don't remember which model of the Badger my dad's is off hand. It uses a paint jar and has a compressor for the air supply and has a water trap in the line.

Strip the paint with ELO (Easy Lift Off IIRC) then wash the parts with warm soapy water. Then use Plastic Cleaner or alcohol. You may have run into mold release agent from the molding process. I do not think Propel cans have water in them, but I could be wrong. Now for your Dad's brush, what kind is it, what is your air source, and approximate thinning ratio? I'm sure the boys will be along soon to help out.
