Has anybody ever tried using vinylester resin to fasten a layer of heavy-duty aluminum foil to the inside of the tank.? Then as far as the gasoline is concerned, you'd essentially have an aluminum tank, and if you had a lot of overlap on the seams, the gas would never get near the fiberglass at all.
