yes he did a beautiful job on that tank .
why not try making your foam core an lining it with aluminum foil , the heavy duty stuff,an build your fiberglass over that ,that would limit the amount of surface area that fuel an oil will come in contact with the glass, or another option is vacuforming theres much info on the web about that an theres many more fuel resistant plastics available , or a freind of mine used to make reproduction parts for the older chrysler muscle cars by using resin an molds , to my knowledge there is a resin formulation resistant to fuel an oil , just cant remember for sure , check it out .
