Firestone Pond Liners AFRRAC1698 Fire Splice Roll Tape for Aquarium, 3-Inch by 25-Feet

I bought this tape to repair a leak in an EPDM pond liner, as an adhesive for a large patch. It was like trying to use taffy. It stuck to itself and was almost impossible to cut. Even though I cleaned the area well, the tape failed as soon as it got wet. I ended up buying a new liner. Maybe if you're splicing under ideal conditions, on a new flat 25' surface, it could work, but I'll never waste my time and money again.

This product was much more narrower than we expected. Ended up using two rows instead. Otherwise a good quality product.
