This stuff is amazing. I thought it was just for waders, but it saved a day on the Green River when my fishing raft had rubbed against something in the car and developed two leaks -- which we didn't notice until we were a ways down the Green. I didn't think this could patch a raft, but it was either this or stop to pump every 20 min. or so. Leaving the boat in the water but turned towards the sun, I put on two coats of this stuff, let it sit for 10 minutes, and it held up the remaining 7 hours of our float trip. I've also used it to smooth knots on fly line or leader so they slip easier through the guides. If it can patch a small hole in a big raft, imagine how well it can patch your waders.
