I bought myself an airbrush and compressor when visiting my brother in law a little over a year ago (UK prices are so cheap compared to Norwegian...). Not done anything with it, other than verifying that it works. With a major work project finishing up in 1-2 months (been over a half year marathon) I am planning to take a week or two off work and feel like assembling or painting some of the models I have carefully stashed away waiting for better times. In that regard, I would really like to play around some with the airbrush, got a bunch of Imperial Guard tanks waiting on assembly, which would be great to paint with the airbrush as well. My worry is what happens with the quality of the air when you use it? I.e. mainly worried about if by using it, if I would be breathing in the paint particles. Do you guys use a mask when painting, or perhaps some ventilation system with an active coal filter?
