I had a few holes in my silicone neck seal on my dry suit, nothing worked to patch the holes until I came across this adhesive. Drop to plug the hole and it saved me $130 on a new throat gasket. The glue sticks the rubber to the silicone, which is what I did to patch the small hole, it cures fairly quickly, around 12-15 minutes, but to be on the safe side I let it cure for 24 hours before I tested it. You can get a larger 2oz tube from another supplier, but unless you absolutely need a large amount I think 0.5oz is good enough and you don't have to wait for it to dry. I keep this in the freezer with other glue and thaw in warm water for when I need to use it again.
