Bob M. from Bainbridge Island, Wa says about Tank Sealer..
“I bought a sail boat that had a leaking fiberglass fuel tank that was integral with the hull of the boat. Therefore it was impossible to remove it. It had been leaking for about 10 years and two previous owners had tried unsuccessfully to repair it from the outside.
I cleaned the tank as per your instructions and dumped the KBS coating material into the bottom of the tank and used a small paint roller to apply the material to the inside of the tank. I removed the excess material from the tank bottom before letting it set up for a week. I put 90 gallons of diesel fuel( that I had removed and stored in drums) back into the tank and am glad to say that there were NO leaks. Your material was easy to apply and repaired the tank exactly as you said it would.
Thank you very much.”
