Ascetone will cut the old tank sealer. A friend of mine, who was concerned as his tank had been sealed, purchased 3 gallons of ascetone, put it in the tank; we rocked the A back and forth for about 10 minutes then drained the tank ; put a couple of gallons of gas in and did the process. When we were finished the tank was clean, he didn't have to repaint, and never had a problem in the future.
