Last night I did two overlays where the hatches go on the inside of my Night Heron deck. This morning the first one I did is cured, the other is not. I realized that I mis-mixed the epoxy, and had put half as much hardener as needed in the second batch. Is it possible to apply a hardener-heavy mix or straight hardener over this to cure it, or do I have no choice but to pull the cloth and clean with alchohol? Thanks!
