First, epoxy is not polymerized by catalysis as polyester is. Epoxy requires
accurate mixing of the two parts; resin and hardener. They are called this
because that's what they are. A mismatch in either direction will leave you
with some unreacted component which will weaken the final product at best,
or leave you with a sticky mess. Alcohol or vinegar will get the uncured
mess off eventually, but that part that cured will probably still be gummy.
If it stuck to the wood, get a cabinet scraper and try to pull as much as
you can off that way.

Subject: [RCSE] HELP! epoxy experts needed
I bagged a pair of wings and a stab 2 days ago. They are plywood
sheeted foam that I put glass over. This was the first time I had
used West Systems Epoxy and the directions said to mix 1:1. When it
was still not very hard today, I carefully read the directions which
said if you don't have the special pumps for the cans, then mix 5:1 by
weight or volume.
1) Is there any way to get the mess to harden. It doesn't have to be
full strength, since the ply is pretty strong anyway. If baking or
something might get rid of or harden the excess hardener, obviously
this would be preferred.
2) If the mess has to come off, how do I get it off the wood without
dissolving the foam?
I sure hope someone has some brilliant ideas. Thanks.
