RE: Thinning Epoxy Resin
Branded,
Check post #26 above, where I discuss my experience thinning epoxy (Jeffco 1310 L-6 / 3102) with "denatured alcohol" from the drug store. I was glassing a balsa-skinned foam core wing with 0.6oz fabric. The solvent did not evaporate quickly enough and, in my case, the epoxy stayed gummy for several weeks, so sanding and filling was greatly hindered.
