When applied correctly, it is easier than Polly, and half the cost and twice the useful life.I have a part 135 operator friend who's done one for himself and one for a customer using Stewart's. He likes it for the absence of smell from VOCs but had to adjust his paint guns and techniques to suit the paints. I'm just finishing a Stits and Aerothane cover and chose it because the best looking older, well-worked fabric planes I know of used it. My last build used Ceconite and dope and while that's easy to use and to repair it doesn't hold up like Aerothane. As for Stewart's? I tried to find some older examples and couldn't. I felt like that made me a guinea pig for an airplane parking outdoors in Alaskan weather. I stuck with tried and true for my project.

all their installation instructions are at U-tube.
When you've never done it, why bad mouth the system?
It uses the same fabric, is stitched the same, has a better glue.
When you consider the cost of thinner for the poly system, you save that much to start, then compare the costs of chemicals, and the Haz/Mat shipping costs. the savings are huge.
Poly is a 15 year system, Stwearts is a 50 year system.
