Ok I tried your suggestions and I found that it was indeed over thin paint. The 3:1 worked perfectly, though I am think for my next round to go with just a tad more as when I was painteing I was not getting good continual flow. As for the PSI, I tried the 10-15 and got horible flow, almost no paint at all. I then increased it to 20, got better but still not great. However at full blast, about 40 psi I was getting great flow. So I guess my stuff is just wired like that, or could my moisture trap be the culpret? |

I had a similar problem and this is what happened to me:
Back when they first came out with the older model/heavier framed airbrush compressor at Harbor Freight, I grabbed one, only to discover that they were about to issue the next model which included the filter/regulator with it.
Since their add-on filter/regulator is only $15.00, I decided to adapt it, but here's the rub; unless I cranked the regulator valve wide-open, since I got poor airflow volume and pressure control for my airbrushes, I was actually getting better performance out of the Testors canned propellent I could pick up at Wal-Mart! So it seems that the aftermarket filter/regulator range is mainly made for a higher pressure model, but it works with my little airbursh model at the wide-open valve setting.
In your case, if it has a few hours on it, your compressor might be weak as well.
Before I jump to any conclusions about my compressor/accessory set-up, I always first try running my brushes on canned propellent just to make sure. If you need a nice adaptor for the canned propellent, Harbor Freight throws in a dandy with their $4.00 single-action airbrush.
Also, Testors now advertises that their acrylics need no thinning for air-brushing. I have tried a couple of their colors without thinning, and aside from higher-consumption of the product, the main problem I get into is with metallic colors, the unthinned metallic paste clogs up the siphon tube in the jar. I havn't tried this with their flats yet, but I would guess they would do all right.
