To add to Steve's post, POR 15 or other tank sealants do seal, for some time. However, it will eventually start to break down. When it does, you would have to remove all of it, which is nigh impossible. My Ulster Rep tank developed a leak recently. I consulted the previous owner who built the car and found out he had leaks around the spot welds for the baffles when he built the car, so used a tank sealer. Once I learned that an experienced welder friend said he couldn't repair it. Solder is the best way to repair tanks. In an earlier post, I had read that original tanks were made and then sealed with solder. This may be accurate, or, possibly like other period cars(Morris) Austin may have used terne plate.
In summary, synthetic tank sealers work, but only once. If there is an issue later on, the tank is junk.
