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.

I tested the hell out of that. No effect. Years of exposure to different 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. I had 50/50 get soft from fuel exposure.
This info consistent with all the other guys that did the same test.

It will make it less attractive for those with fiberglass tanks. Alcohol/gas mixes are more aggressive than either gas or alcohol alone.

By the Farm Bureau Paper it is stated that Wisconsin has passed a law that all 87 no lead will contain 10% alcohol and that nine other states are considering it.  It didn't mention the other no lead grades.  Here in Michigan it is under consideration at this time, and there is a good chance it pass.  Other than cutting the power some what, is going to effect the operation of the rotary in some other way.  JohnD
