I'm sure everyone has noticed that the original paint jobs on these tractors, or for that matter just about anything factory produced, is WAY thinner than what we end up with when we repaint them. Factory paint films are usually in the 1.5 to 2.5 mil. range, and repaints are seldom less than 4 to 6 mils. One reason for this is that the factories used very high pressure guns with the paint thinned down a lot more than what we use. And they were equipped to force dry them which lessened the number of runs. That made for a thinner coat that still leveled out and looked good, and it saved on paint. For years I have used an airbrush for anything other than hugh jobs such as a whole automobile. The paint needs to be thinned a bit more. It gives a LOT more control for where the paint goes (gets into tight spots great), and the film levels out much better than one from a full sized gun. In fact most films look like wet glass. And because the film is thinner, I use less paint, and it dries much faster, and cures much faster and more completely. It also doesn't weigh near as much and can be used all day with little fatigue. Airbrushes and the small compressors needed for them also cost a lot less than conventional set ups. About the only drawback is that since it uses much less paint and I don't have to mix as much, it can be hard to get accurately downsized mixtures of hardener, etc. I use a Pasche "H" airbrush that is over 20 years old. It is single stage, but has three different tip sizes that will handle patterns (only round patterns but is not a problem) from pencil thin at barely 5 psi to 3 to 4 inches at over 90 psi. I have noticed that the newer versions of this airbrush come with plastic pickup tubes that may not stand up to laquer, but these tubes can be replaced with brass tubing if need be.
