I bought the 5' roll of clear flex seal tape and was going to fix a small spot on the bottom of my boat and I even cleaned the area really good let it dry overnight applied the tape it looked to be stuck good and seal off put the boat in the water the next day and the tape peeled loose in several places and was leaking glad I caught it when I did would have sunk my boat
In other words I would not waste my money on this product it is misleading that it will fix boats
