I'm back AGAIN! I was spraying Model Master Acryl gray primer, Just like last time, and I wiped the tip with Windex and it doesn't do anything for tip dry. Paint would not come out, there was primer all over the needle, i cleaned the needle, cleaned it again after every time it clogged, and so on. My airbrush is flooded with primer on its insides, paint got into the air valve, and I don't know how. Its also in the trigger mechanism and past that...
