One of our club members fabricated a nifty water quencher. He had a coil of copper tubing made that fit nicely in the bottom of a 5 gallon bucket. Compressed air was routed through this tubing, which sat in the 5 gallon bucket, buried in ICE. At the end of the copper tube was a big water trap and then the line going to the paint gun. All that hot humid air coming out of the air compressor was cooled down, any moisture condensed and then trapped. We also put an inline trap at the gun. Same philosophy as the refrigerator water trap mentioned.

Stewart Systems does not recommend Turbine systems, this was tested and found to be true by another club member. It is also a water borne paint system, and as such is incredibly sensitive to moisture in the line. We have learned that the hard way on the three gliders (So far) that i've been involved in refinishing with the system.
