RE: Fabric covering questions
Hi there, and welcome back to the addiction. I've used Koverall for the last half dozen or so planes that I've built. My experience has been that you'll really have to pile it in to mess up the covering where it'll rip or tear. Our field is sometimes surrounded by wheat or hay, and the stubble that is left will shred the iron on coverings. You might get a dent in the koverall, but then it's a simple matter to heat shrink it back to shape. I've not had anything poke a hole in it or tear it. It's really tough stuff. Best of luck.
