I'll second FHHUBER's recommendation. you may even consider heating the epoxy after aplication by using your heat gun on the general area. Do not get it so hot it bubbles, just very warm. This will make the epoxy wick into the tiniest cracks and crevises and speed cure time a bit. It will definately strenghten the area. I also drill a 1/4 inch hole at the lowest spot beneith the fuel tank to drain any accidental spill (you never know when a hose will slip off or a tank will split). This sure makes cleanup easier as well as gives quick indication if you ever have such a problem.
