I just had some work done to my tank and I'm thinking I should use one of these sealers to prevent any rust from coming up. I had the bracket that holds the fuel pump and fuel sender welded from a newer tank. The tank is in excellent condition except that the welder had to clean up that area and do 4 small welds. Besides these few, what other kits are out there ? Im not even sure if I need it ?
