According to Wikipedia denatured alcohol is also used as a fuel. So maybe the "burnable ethanol" is what I need.

In terms of the current usability of the epoxy resin, it just tears the glass apart when I try to brush it on. That is, I brush on a coat of epoxy, then lay on the glass, but when I try to "paint" on another coat to saturate the glass, it just tears the glass apart.

Good think I'm trying this on a test piece!
