Here's the problem. I'm trying to spray Model Master enamels with Aztec's A470 double action brush. I'm using Testor's airbrush propellent can. Before painting, I place the can in a jug of luke-warm water, and leave it there while (attempting) spraying.
The brush loses all pressure within 2-3 seconds of spraying. Let it sit for a few seconds, and it will spray agian, albeit only for a few seconds before losing all pressure. After about 2 minutes of this, I noticed the airbrush was getting very cold. I checked the can to see how cold it was. Funny this is, it wasn't cold at all. However, soon the brush was spitting out ice. Obviously the propellent is freezing in the airbrush itself.
I've gone through 3 cans of propellent in the last week. (I'm painting a 1/16 Tiger I). Everything up to this point has gone smooth as silk, as long as I kept the can warm, the paint went on like a breeze. The airbrush never iced up, and only the can itself became cold.
Anyone ever had this problem before?
