Have you seen the TV commercial where a man cuts a metal rowboat in half, then uses Flex Seal tape to join it together again, then use in the lake? Well it works! I had to join two pieces of pondliner together, used Flex Seal tape, and it works just great. And works underwater too, but mine is out of the pond. Works way better and faster and cheaper than standard EPDM pond liner tape. And the Flex Shot clear adhesive works perfectly on the leak where the hose goes into my filter box. All stores carry this product now. Do you think they will give me product endorsement pay now??? Great product!
