I make mainly belts, guitar straps, banjo straps, masks and some fetish stuff. My confidence level is pretty low with my sealing process. I think of it as a crap shoot and dread getting a complaint that someone got dye running all over their clothes. Hasn't happened yet though. So I usually overkill with many thin coats of whatever I'm using, whether it resolene, tan-kote, etc and hope it holds.
