Good luck with it. Hopefully it will work. Note the rubbing alcohol method only works with breathable GoreTex or Toray waders.

@@tacklevillage5650 yeah these are definitely not GoreTex and I know nothing of Toray. I'll let you know how it goes.

@@tacklevillage5650 short story: it works on the exterior. I applied it to a CROTCH SEAM leak on neoprene insulated waders and it stopped it. For good measure i applied a dose on the inside as well. On the breathable waders it seems to have stopped the leaks on the two spots I treated however I am pretty sure i have a 4-6 inch diameter area around the knee that needs to be treated. The knees get abuse for sure and i imagine i have dozens or more tiny little pinholes all over that area. I have tried the isopropyl method, dark room/flashlight, soapy suds and air, as well as a failed attempt of submerging the leg and trying to fill it with air from the inside. Nothing conclusive so my next attempt will be to slather the aquaseal all over the knee area and hope i catch it all. Not sure if it's worth it but new waders are expensive. I might use shoe goo as a protective layer afterwards to protect the knee areas
