I have a guy out here in PA that does all my tanks. Hes actually my radiator guy too. He cuts them open from the bottom and sandblasts every square inch inside and then does professional body work quality job getting the cut pieces back in. We had a problem with sealer turning to tar and ruining the engine in one of my customers cars. This was the only way to fix it. The sealer itself is designed to resist most chemicals.
