I just did some touch up on a bedding job I did a couple of weeks ago. I basically just wanted to fill the front of the barrel nut region a little further up. I used the same epoxy I purchased from stockys. I did everything the same as I have before, removed the barreled action after 12 hours, everything seems good and looks good. When I went to start cleaning it up a little, removing the release agent and such, I noticed that the epoxy is a tad bit spongy. I checked the stuff that I had leftover in my mixing cup and its hard as a rock. Could it just need a bit more time? Its not tacky, its just a little spongy. Can epoxy sometimes take several days to cure or is it basically just a botched job that will need to be redone?
