Thanks. What you guys do to the plastic models is simply amazing. Absolutely incredible workmanship. It is not possible to paint a plane of this size with an airbush. It is just too big. I found a good technique that works for me is to use a really good HVLP spray gun and get the lines as close as possible with the least amount of overspray. Then I work on the line with the airbrush from each side to remove the coarse edge a little at a time.
