How do you get a nice clean edge cut when the cloth hangs down from the upside-down hull? I imagine the epoxy will wick into the cloth below the shearline despite best efforts to only apply it on the cloth lying directly on the hull. Can I use scissors to cut cloth that has green epoxy on it? I have used a utility knife to trim glass off the edges of butt joints but in that case I could place the panel so that the glass was on top of a hard surface to cut against. With a hull, I'd be "cutting against the air."
