I really like Koverall too, especially after trying Dave Brown Skyloft. Like 2fast, I found that Koverall seals in two coats, whereas the Skyloft requires endless daubing on the larger holes to get them to close up.

Someone mentioned putting on Koverall with slightly thinned Weldbond. I tried that with the Skyloft and it worked very well. I painted on the Weldbond with a foam brush, let it dry, and sanded lightly. Then I painted on a second coat. I put the covering on wet, and ironed it down to the dried Weldbond. On a test piece one coat was not enough to get it to stick securely, but with two coats it stuck so tight I couldn't pull it off. It added tremendous strength. Unfortunately the open frame parts were incredibly frustrating to seal. Koverall doesn't have that problem, and should go on just as well with Weldbond. Jim
