Help!!!

Fox,
The best thing to do is to get a book on airbrushing techniques. It would give you the basics of airbrushing. Even with a good guide, you will need to practice, practice, practice!
I got a really good guide from my local library. There have been some excellent articles in back issues of FSM also.

Desert Fox,
Here are two books that Kalmbach prints
that are available from FSM and Model Railroader.
How to Use an Airbrush by Robert Downie
Painting and Weathering Railroad Models
by Jeff Wilson
They have information on cleaning,practice
exercises weathering etc. Osprey has a good one available
but I don't remember the name at the moment. Check out
the books and keep practicing.Hope this helps.
