| I agree with Ken. Vinylester resin is safe for use around alcohol and alcohol related substances. My whole airplane is made from vinylester. However, vinylester will NOT adhere to any epoxy layups. So, don't try to put it on top of any other epoxy resin types. I believe (with emphasis on "believe") that vinylesters will adhere to polyester resins.
Vinylester was originally formulated to make underground gas tanks. On Jan 18, 2006, at 7:49 AM, Ken Welter wrote: 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. Ken Welter
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.
