Is Klass Kote flexible for fabric?
Pretty much but when I use solartex it has been during the summer when I do most of my building and I cure the covering before I do any type of trim work or painting. I cover the plane and shrink then set it in the hot sun then take it back in the shop and shrink it tight again. I do this until it no longer sags or wrinkles. From then on the heat and hot sun no longer has any effect on the covering.
I don't use dope these days for much of anything so I didn't know the KK wouldn't adhere to butyrate. KK will flex within reason, it isn't brittle.
