Just watch if your using a blue Testors Propellant can not to put the air on too high. The air comes out liquidy and spray's really thick. I had that happen and it scared the living daylights out of me. It has been half a year since that and haven't been airbrushing since. But don't let me scare you off. Airbrushing is just cool when you see the finish you get. Another reason why I haven't been using it is because it is so cold, it even takes the tamiya acrillyc a day to dry!
