Flex Seal repair on grey tank.
Have any of you used a Flex Seal product to repair a crack in a holding tank?
Forum Discussion
If the crack is in the bottom, in an area where the tank is going to flex a lot, and not well supported chances are slim an adhesive will last too long as the tank fills and sags.
You may want to look at adding a support under the tank to take some stress off of it.
