I've painted a couple of planes. It's a major PITA! However, once you get set up correctly with the booth, proper filters, lighting, joists for hanging wings and things and compressor system. I found out the hard way about having the right compressor with enough CFM as well as moisture removal. What was the most odd thing was the bugs attraction to the paint smell, especially yellow jackets. I had a B-52 bomber fly get into the booth one day and I chased him around with the spray gun. I got him coated up pretty good until he did a nose dive right into the very tip of my wheel pant. So I have a fly wing embedded into my 1st RV-6 wheel pant. Painting is one of those things that you can 99% of your stuff right and that 1% thing can screw you up and you have to start over. Spraying paint with pearl in it was the hardest item to master.
