I have tried the Flex Tape and the Flex Seal spray. Neither of these items have worked. I had a spot on the roof and used two cans of spray, but the leak was not affected. Since that experience, I decided to purchase a roll of Flex Tape to mend some hoses. I tried it on four different hoses with leaks in different places. The leak was not stopped on any of them. The best sticking that it stuck my fingers together but not anything that needed repairing. I think their advertisements are lies and I am concerned that because of the boat advertisement, someone will try to mend a boat with it and wind up getting drown. I would not recommend this product to anyone.
Bottom Line: No, I would not recommend this to a friend
