Re: question on Waders
I think you will find a split or tear will hold better if you use a thin piece of material over the repair. A piece of rip stop nylon will do nicely along with the Goop.
1. Get some Goop in the rip/seam and hold the pieces together so there is no gap and let it dry.
2. Now cut a piece of nylon that fits over the seam/tear with an inch on each side of the rip/seam.
3. Take a cheap paint brush and spread the Goop over the out side of the repair and wider to fit the piece of nylon.
4. While everything is wet place the nylon patch over the area on to the Goop.
5. Paint more Goop over the nylon patch so the nylon is well covered. Keep the coats thin and the repair will hardly stick up above the neoprene. Go over the edges of the nylon with the Goop so they wont get caught and pulled up.
With a little imagination you can get a really good patch that will last a long time. You do need to make sure the neoprene is still good. There is no need to repair neoprene waders is the material is deteriorated. If you can easily tear the material I would not repair it. It will just fail again. If the failure is a failed seam because the sewing broke or you caught it on something and it ripped, then go ahead and repair. If neoprene is not stored properly in a hot environment it will eventually deteriorate.
