   I have glass tanks made with Vinyl ester resin in my coot and I have had no problem with Alcohol/gas blend in the tanks or with the engine ether.

I agree. I have Safety-poxy/EZ-poxy tanks. I burn 10% ethanol every winter, no problems whatsoever.

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.
