I've got some GreatPlanes Pro epoxy finishing resin that I bought to use for fiberglassing. This is pretty thick stuff and will absolutely have to be diluted to use with the delicate fiberglass cloth. I know people use alcohol to dilute epoxy but I'm afraid that I'm not up on my types of alcohol.

I picked up something that in Japanese is labeled as "sterilizing ethanol." There was also something called "Flammable ethanol" (which was much cheaper). What kind of alcohol should I be using?

BTW, three hours later my "text mixture" of the epoxy is still soft and sticky.
