GL: fiberglass tanks and ethanol

[bob Austin]

If you can coat your tanks with epoxy, it will prevent the problems with the
polyester gel coat.  You have to have good access to the tanks (ie manhole),
be able to get to all sides of the baffels, and the entire surface of the
tank.  The gel coat must be cleaned of all waxes or varnishes, and I would
clean with acetone, and sand lightly.  Then put on three coats of epoxy.
