Anyone have the absolute, hands-down, definitive answer on sealing fiberglass fuel tanks? After a couple of days Googling NTSB reports and builder horror stories I'm afraid to even put a fuel tank on my plane, at least one that might need to hold fuel with an alcohol additive.
This stuff sounds wonderful, I guess. http://www.caswellplating.com/aids/epoxygas.htm I don't need 3 gallons of this, and they don't say anything about alcohol. http://www.aircraftspruce.com/catalog/cspages/tankseal.php Randolph 912 is supposed to be another option, but I haven't been able to find it. Finally, *almost* everyone claims that vinylester resin is impervious to fuel with additives, but I was able to find a few posts on the net saying it isn't. In other words, I'm confused. Any advice appreciated. Thanks, Bob
