Review on 3M Marine Adhesive Sealant 5200 (06501) Permanent Bonding And Sealing For Boats And RVs Above And Below The Waterline Waterproof Repair by Bobby Plymell

Do you have an above ground pool? Or any pool with a liner? BUY THIS! NOW! My brother had a big crack on the bottom of the pool. It crawled in all directions. I placed the BLOB on a disposable spatula and dipped. I hand it out like a three-year-old with icing on the cake. (Pool was already 9 years old, this was his last fight.) 4 YEARS! later, NOT - A - DROP! This thing heals underwater! There is nothing like it! We've used it on our boats since its inception, but the POOL? ! ! It saved us a thousand dollars! Warning. It hardens once opened, so don't plan on using the tube more than twice. Used once without a cap. The second time I pierced the hardened end and benefited. Until the third time? I had to pierce the wall of the tube and get out everything I could. But even if you only get one use, it's worth it.
