Bubbles in paint jobs

Q: I've read lots of articles on using an airbrush, and have had some good results, but my last few paint jobs have been ruined by little bubbles and spots in the surface. I'm sure they're not specks of dirt, because I'm careful about cleaning the model and my spray booth before starting to paint. They're not "fisheyes," either. Any idea what could be wrong?

Ken: The little bubbles you describe could be caused by moisture getting into the paint somewhere between your compressor and the business end of your airbrush.
 
Check all of the fittings, beginning with the compressor outlet and working up to the airbrush.Check every washer, connection, and anywhere air (and moisture) could be entering the system.  

Also, take apart your airbrush – all of it – and clean every orifice, nozzle, needle, and fitting.

Depending on the make and model, check the washers and replace any that look worn or damaged. Check the fit of the paint cup, too.  

If you don’t have an inline moisture trap, drop everything and get one.  Install it in the air line, as close as possible to the airbrush.  
As a last note, avoid painting on really humid days. Good luck.
