Hey My brother and i have just bought an airbrush! But we have never tried one! IT would be nice if anyone have an articel on how to use an airbrush! Also about cleaning and hints to how to make the cool effects like dust and how to shade with the airbrush! It would be nice if anyone have that!

If we knew what make and model, some one probably could answer your questions.
I suggest you read through this forum, and the painting and airbrushing forum, as most of your questions have already been asked and answered many times.
