Yep...Aguaseal is the absolute best-nothing compares to it. If you have multiple spots put saran wrap on the wet stuff so you can work on the others without getting it all over. It'll cure fine and then you just peal the celophane off after it dries.
check out a diver supply store (yeah yeah yeah...in the center of the country not many diver supply stores but you never know) or a boating store, like west marine or boat u.s. They probably would have it at a sporting goods store, but down here it is sometimes hit and miss as to what a sporting goods store actually carries. I have to get some too for all of my waders.
That's a good bet Wisboz. They also make a kicker called Cotol and you can brush that on the Aquaseal to cure it faster. I don't use it very often unless I'm on a trip or need the waders to set really fast. I guess what I'm saying is...don't let them talk you into buying that also unless you need it to set up super faster.
Aquaseal is great stuff, but make sure you store it in the freezer after you break the seal. Even if you put the cap back on immediately after use the entire contents will cure up in the tube at room temperature.
