a said it way earlier, and I will repeat myself - I see nothing that more time and practice with the brush will not cure. I've been using a Sotar since maybe the mid 90's, and have well, a few of them. Learn the paint reduction the brush likes, and it will reward you accordingly. Continue to try to push stuff it does not like, and you will remain frustrated by it... It is a trait that can be associated with the Sotar head that when you first depress the air, it will give a small paint splat - usually a very light ghosting of color. I have just learned to accept it, and work in a manner where it does not effect my outcome with the brush. Keep a small scrap of paper near your starting point, initiate you airflow over the scrap, and then move to where you want to work...
