Another epoxy to consider is Jeffco 9700.
This is the fuel tank coating reccomended by Velocity. The Jeffco is
designed as a fuel tank coating and does not require post cure heating as the
Pro-Set combination requires. According to the Pro-Set web site the 145 /
226 combination requires post cure heating; " Post-cure heat -- 110°F to 180°F (43°C to 82°C) will accelerate the cure
and improve the physical properties of the cured epoxy, and is required
with 145 Resin mixtures to reach an acceptable degree of cure.

Way to be thorough Wendell! I encourage the mason jar test too, just to
make sure.
I'm building with epoxy and was using West Systems
because the boat people recommend it for fuel tanks. Out of curiosity, I
e-mailed West Systems questioning the use of their epoxy with fuel with
alcohol. They did not e-mail back but quickly phoned to tell me that
it would not hold up to alcohol and suggested using
Pro-Set 145 resin with Pro-Set 226
hardener. I used this as a coating on the Cozy tanks and also to
bond the top skins onto the tanks.

Al,
Your statement below could lead some to think
that by adding more hardner to an epoxy mix that you could make it more
resistant to fuel. I don't think that is what you meant, you might want to
clarify it *and* provide the name/model of the epoxy that you
tested.
