My first brush with acrylics...ugh.

All,

Last night I airbrushed Testors Model Master Acryl for the first time, and I had mixed results. I was spraying gloss white and basically,it didn't stick very well. I have a basic, external mix, single action airbrush, but I was pretty happy with the spray pattern I was getting. I thinned the paint, trying for "the consistency of milk" with the Testors acryl thinner (I know I could use other, cheaper stuff, but this is my first time using this paint, so I thought I'd play it safe).

Anyway, I was spraying the inside of the air intakes on the Monogram 1/72 F-4J I'm working on. I think I was able to get a pretty good dust coat, but if I stayed on the piece a little too long, I got paint pooling (not running, just collecting at the bottom of the piece). I'm thinking that I may have thinned too much and not been patient enough to do several light coats.

Still, I previously sprayed good old Testors square bottle enamels, and they clung to the model (cockpit) without a problem at all. Are acrylics really this tough to use? I'm going to work with the mixture of paint and thinner and maybe make a thicker mix, but does anyone have any other hints?

Regards,
