I thought it is Hypalon. I have been looking for that stuff for a while. No luck. Someone told me I can use neoprene or urathane (I can never figure out how to spell), But forget what brand and which product. Most of the stuff I check out are made for wood application not cloth. I'm currently contemplating to build a skin boat -- want to feel how those Native American did it so many years ago; but I DO NOT and CANNOT use seal skin. Well, I guest canvas is the cloest thing to seal skin. I want to find out the brand and the product name ; preferably how to use them. Any help is greatly appreciated.
