RE: Epoxy Not Setting?
Hello,
I would not let epoxy cure in temp less then 70ºF, some epoxys require a post cure at a an even higher temp, I just put the parts in my black topper on my truck on a hot day and it will get the job done for aeropoxy.
Same as what the other people said careful with old epoxy and mix ratio.
Make sure you have it thoroughly mixed. A lot of epoxys have a die in the hardener when it turns to a constant color with no strands of hardener it is mixed.
