As some of you know, a while ago I purchased a new airbrush, as recommended by Cyril. In itself the airbrush works fine and I like the idea of having a regulator on the airbrush, but the quick release connector has been a real problem. I noticed a difference in the performance of my older airbrush when I connected the quick release connector to it. I wasn't 100% happy with the perfomance of the new airbrush either, but I persevered with it anyway. To cut along story short, I was experiencing problems with the trigger not releasing properly after I took my finger off it or air backing up into the paint cup to mention just a couple of the problems. After stripping them down and endlessly cleaning them, and then thinking I was thinning my paint to the wrong consistency, I decided to go back to the air hose without the quick release connector and I am a lot happier with the performance of both airbrushes. They are both performing as I want them to. I can only assume the quick release connector wasn't letting enough air through for the trigger to shut off after I released it, even though I had my air pressure set at 20 psi plus.
