The last few fabric covered gliders i've been involved with have been done with Stewart Systems covering process. They strongly recommend the DeVilbiss Finish Line IV HVLP gun.

Thanks, Tony. It looks like the DeVilbiss is standalone? I see good reviews of it, but I'm kinda looking at some of the $200 range HVLP guns that come with a compressor and a long length of hose. Our big standard air compressor always has a bunch of water in it, and even decent filters only do so much.

I know that the HVLP compressors heat the air more than desired, but I've read that a decent length of hose will help cool it. I'm using Poly-Fiber, and plan on adding reducer to help counter the heat, as well. I have read that it's best to stay away from the Harbor Freight HVLP tools, as they don't deliver an accurate pattern and fail after a short life.

Again, thanks for the help!

A refrigerated air dryer can fix almost all moisture problems. You can find small ones on ebay frequently for not a lot. I have a 5 hp compressor running pretty much all day feeding the CNC machines, tried all kinds of filters without much success, after installation of the refrigerated dryer everything downstream of that is bone dry.
