Flex Seal repair on grey tank.
Have any of you used a Flex Seal product to repair a crack in a holding tank?

We used on a crack in the tank of our commode in our S&B several years ago. We put 3 coats on it, letting it dry the recommended time specified. It lasted for about 2 years before it began leaking again. I wanted to dry, spray and let it work for another two years, but DH decided he would rather just get a new commode.
