I have come out in the morning to find the parts have shifted and epoxy is easy to soften with a heat gun and the parts can be re-glued. Last summer I started using Sigment again when I built a stick frame up, it was all hardwood sticks and CA wasn't working for me.
I'm a CA user though, I do once in a while get the reaction but after I had a bad reaction and figured out what it was I can tell when it's time to quit building and leave the shop.
