I used the Chick method. That may be because I wasn't smart enough to know about Quick Fair at the time. Occasionally I had to go back and add another coat of epoxy (or, better, slightly thickened epoxy) after some initial sanding as the skin was getting too thin and the cloth tape was coming through. I was happy with the results and felt the structure stayed strong. But it was noisy, dusty, and tedious. You all know better than I do, but I'm assuming Quick Fair is suitably strong, not just a "skin"?
