Recently my gray nozzle on my Atec airbrush stopped working. I always spray a fair amount of aztex airbrush cleaner through my nozzels after painting but even this didn't help. Plenty of air was coming through but no paint. I contacted Testors to see if they could give me any tips on getting it to work. (Actually I was hoping they would send me a brand new one.) The fellow that replied to me said the plastic used in the nozzels was such that it wouldn't be damaged by most solvents. He suggested soaking it overnight in a different solvent. I tried some orderless paint thinner I had and it worked like a charm.

Rodger:

This is good to know. Thanks for the "tip" (no pun intended :-) :-) )
