My first attempts at airbrushing are proving difficult. I just got a new gravity-feed, dual-action brush, model GD102 from Airbrush City, to use on airplane and knight models. Hooked it up to a Paasche D500 compressor. Airflow is fine. For my first trial runs, I tried two Testors enamels, their ordinary gloss red, and a metalflake glossy, Model Master "Plum Crazy," diluting both to the recommended milk consistency with Testors airbrushing thinner. The red worked OK, except that to get it to flow through the brush, I had to dilute it so much, about 50/50 or even 40/60, that it covered too thinly. Even at that dilution, the plum would not come out of the brush at all, even wide open w/ maximum pressure. I diluted it way down, about 2 parts thinner to 1 paint, maybe even 3-to-1, and still barely got more than a few tiny splatters coming out. Yet when I cleaned the brush, the thinner sprayed out just fine. Can anyone tell me what the problem is? Is there some adjustment needed to the brush? Do I have a defective brush, or is this the wrong brush for this type of paint? It's a brand-new brush, never used before, so I don't think cleaning is an issue.
