I posted this on another site but would like to know if anyone here has tried it. I just saw a video on fiberglassing your plane using polyurethane instead of resin. It looks like the same process as you would use if using resin but instead using polyurethane. If this works it would have alot of benifits. Clean up would be easier, material less expensive, less smell, and easier to work with. So has anyone here tried it, I plan to try it on a scrap piece and see how it turns out.
