Just minutes ago, I did a test spray with another potential problem color by pouring the thinner (Vallejo) into the airbrush reservoir before adding the thick acrylic -- that seemed to help -- maybe. I'll keep testing.

It looks like fuzz or spiderwebs, I had this with some Mr. Surfacer I was using. It was drying too fast before it hit the model. I thinned it out a little with some Mr. Leveling thinner, reduced my air pressure and moved closer to the surface. That seemed to work.

If it's acrylic, it's may be a problem with drying too fast, like Jeff said. Maybe try adding a drop of retarder medium to the mix.

... Airbrush is a Passche VL series at 40PSI. Paint is un-thined Tamiya Acrylic.

Any ideas?

What kind of Vallejo ? Model air or model color ?

Vallejo Model Color 'Desert Yellow' (70.977).

When I use model color in my airbrush I only thin with the Vallejo thinner, the new clear stuff made to "turn" the model color into AB ready paint. I know other stuff has worked people but I have found this to be my best bet. I add the thinner and some of the golden airbrush medium and I paint at about 15 to 20 psi with little issues.

Tried again tonight. I reduced the pressure to 25 PSI, and thinned the paint to a 50:50 ratio using my preferred thinner(70% isopronal rubbing alcohol).
