Don't waste your money. I tried it on a cutter seam that leaked, and it did nothing...waste now just leaks from the edges of the tape. Then I tried it on a small crack in a pool skimmer. I stuck a piece in the outside AND one on the inside where the water is but big surprise, it didn't even try to stick underwater. False advertising that it works underwater or with water. It might patch an air hole, but if water is involved, it won't stop it at all. What a joke.
Bottom Line: No, I would not recommend this to a friend
