Attempt at painting...

Fathom green, that's the color.
It was popular in 60s early 70s chebbys, dark mossy green with tiny flecks in it.  And a pain to paint with though.

Sitrep:
Temps high 60s low 70s.
Have compressors hooked up,
Have fans and new filters.
Have time.
Ready to paint right?
Yes and no.

The mix is 8:2:1
That's 8 oz paint to 2 oz reducer/thinner to 1 oz wet hardener.
H.f. "pro "paint gun, New moisture filter.
I tried mixing half a batch of the "starfire s.s. urethane" to try out my prowess with real paint since the primer went so awsomely.
I got spitting and more of a wall texture/ micro truck bed like coating.   This stuff is pretty forgiving, as long as it was still wet and enough went on it flowed the globs & blobs together nicely.
  Only comparison I have is to a high quality spray can.  The cheap ones are thin and run and the better ones have more pigment and bonding properties.
Since I tried it out on the trunk and underhood first I let the defects stay there until it gets figured out.
  Next mix I did a full batch and  added an extra ounce of reducer to get more of a liquidy flow w/o problems.  Initially it shot great
And after stopping and repositioning the spitting started happening some again.
The second compressor wasn't coming on when it was supposed to so air was low and the 25 gallon was working its a** off.  I was able to shoot for max 20 seconds before I lost pressure and it came back on.

So I'm in the process of trying to get the mix right, fan pattern has little effect on it, air flow probably needs more, paint flow /trigger pull has some effect on the spitting.

Mtf...

 I have gotten some indication that there is more need for airflow mainly, needing to keep the gun a constant distance from the panel, not thinning the paint too much, not under thinning it.
Its a confusing balance.  Anyway I need another big compressor for airflow.

  1. Couple suggestions: if you take the cup off of the gun, there is a conical filter (like a screen). Throw it away. They cause symptoms like you are experiencing. It is not needed as long as you strain the paint.
    Make sure you set the air pressure regulator with the trigger pulled. You need ie. 28 lbs pressure at the gun with the trigger pulled.
