The seminars we do are exactly that, hands on to see how the system works. I would simply ask that, before you criticize our system, that you get some training and than make an educated decision if the system is for you.
Marty - I have seen the test panels from seminars. They look good. They are only about three feet square. I have not seen, in person, an entire aircraft done to the standards of those test panels. I am not spraying iso-cyanates, so personally I shall stick with dope.
My comments are based on my buddy’s J3 restoration. He bought the exact equipment Stewarts recommended, including the gun, nozzle, and high capacity compressor. He built a huge spray booth with intake and exhaust fans. He went all the way to central California to get tips from an expert.
He is a hobbyist, like me, but a better engineer - when he measures your top coat he does it exactly the way you recommend. He carefully times and shoots. He pays attention to ambient temperature and humidity. I could never do any of those things - maybe that was why he was VP of a major engineering firm and I was a lowly engineer.
Results are mixed. Some areas glossed out and others didn’t. He sanded and tried again. Better, but still my Cub is glossier, having been sprayed with a Binks 37 in my driveway in 1981. I have seen a glider he painted in solvent based paint, and it was impressive.
I think that a hobbyist should spray an entire wing before electing the Stewarts System. That is just an opinion based on watching my buddy’s struggles. A pro shop may not need to do that.
