Sounds like too much pressure. The gun is spraying "dry". I was noticing that from your pictures, yet it also had a mottled look. Mottling is when you have patchy light and dark areas in your sprayed panels. Lighter tan metallics are very suseptible to mottling. I'm wondering if your reducing package is too slow and your spraygun is set up to spray too dry.

The mottling could be because you are spraying outside. The variance in even light winds can affect color consistency.

To try to find out if it is an HVLP gun. That will be very important on the setup. Also, is there a model number? I used to run conventional guns from 30-45 psi and HVLP from 7-17 psi. I would start with what the manufacturer recommends.

Another issue could be with your compressor. Does your line filter have a regulator on it? You need constant pressure for the best appearance. If your compressor does not have enough volume to keep the pressure constant, then you have trouble controlling your application appearance.

And definately run up and down the panel like a robot. That also could be the cause of the mottling. For the basecoat, you want to apply it just to hiding. As soon as the primer is covered, that is enough. too thick a basecoat will hurt appearance and can cause other issues like cracking.

The reason this is strange is usually the dryer the application, the less the mottling. You've managed to figure out how to do both at once. The effects guys would love you!
