I used to work at a radiator shop 20 yrs ago& we did lots of gas tanks for all sorts of vehicles. we soaked them in a tank of hot caustic soda ,then washed them with high pressure water,the repaired any leaks. However now days the soda is not legal, at least in the houston area.
Well mcdroid, if you wind up not being able to find anyone down there to do a good job for you and don't mind being without a tank for a little while, ship it up here and I'll have the guy that did mine do yours. You might even be able to ship it to him directly.
