started to work with Auto Air colors years ago. Learning curve was steep but the introduction of Createx‘ 4030 made life easier. I shoot it through my H&S Evolution 0,4 mm nozzle with 25 psi although 0,6 mm nozzle seems to work a bit better. One recommendation as indicated also in the videos, try to let the paint sit for about 10 minutes after mixing with 4030 flow enhancer and 4012 reducer.
