Hey welcome to the Herd!

Airbrush: Practice, practice, practice. I just bought a new one as well and now i have to learn the process all over again. Keep it cleaned and maintained and it will last you a LONG time. When I clean i use lacquer thinner to get the color out, then shoot a little alcohol to help soften the harshness of the lacquer thinner. If you have a cap for the needle end, use it when the you're not using the brush. When you've gotten more used to the brush, you'll love the results.

Nice work on the pilot BTW!

Cheers.
