Do a forum search with "stewart paint" and you will get alot of great info. Plus if you haven't already seen Stewarts training videos on youtube...check them out at......
I used Stewart Systems etching wash, primer, and paint on my RV-9A. Yes, I would use it again. I had to experiment more than I liked to get my fluid flow numbers right for my gun (a high quality IWATA), but the results turned out pretty good, and I often get positive comments on my paint job.
It was really great to clean the gun in the laundry sink. You must have humidity below about 70%, and temperature above 70 degrees.
