We used the Belzona 1121 on our water tanks, two part, easy to mix and apply and (I don't want to jinx us) but the tank doesn't leak any more. It is very expensive though, but it kept us from having to take our tanks out (lots of wood work required) and replacing them. Our alternative was looking at plastic tank inserts, an idea we didn't really like but had been recommended.
