Hi there MAXUS ...
An "unofficial" welcome to the FSM community forum(s) ... glad you stopped by and joined up. I hope you will stop by often, read alot, post alot and share your part of the hobby with all of us, as we share with you.
The Aztek airbrushes have served me well, airbrushing is an on-going learning process ... just about the time I think I have got the answers ... they change the questions ... <grin> ... or so it seems.
If you post your airbrush questions under the Techniques forum you will get some opinions as to what you should and shouldn't do.
Again, welcome and have fun!
