Al,

You must be speaking about Polyester as = Epoxy must=20 absolutely maintain a strict ration mix, as per manufacturers = instructions,=20 to allow proper molecule to molecule bonding of the hardener = and the=20 resin. Polyester on the other hand has flexibility in that, more = hardener=20 promotes hardening sooner.

I tested the hell out of that. No effect. Years of exposure to = different=20 batches of known alcohol. I understand that if you use a resin of high = proportions of hardener to resin, it's resistant. If you use 50/50, it = isn't.=20 I had 50/50 get soft from fuel exposure.

This info consistent with all the other guys that did the same=20 test.
