I once had a 63 T-Bird that had a pin hole in the bottom corner of the tank.It was not rusted it was kinda sliced do to the fact that the rear hung real low and getting to back road parking would hit bottom. I used a Old epoxy called PC7 cut a patch from alum siding drained the tank sanded it- may be 3inches around to bare metal.put it on the patch and smusched it on the area.Let her sit for a day .That patch worked 8 years that i know of till i sold the car.Wish i never got rid of the T-Bird in 1977.
