definitely takes a good sized iron, and cleaning with acid so solder will stick, and they use copper shim stock to bridge holes with, another method I have seen used on tanks that could not be replaced was a light sand blasting and a coat of fiberglass over the bad area, such as a tank with multiple pin holes, not only seals it but reinforces the weakened area as well, I do not recommend these procedures if a replacement tank can be purchased though, In a message dated 1/27/2010 12:43:20 A.M.
