Hey guys,
Last night I whipped up a batch of Devcon 30min Epoxy for my Sig Somethin extra and when I woke up this morning the mixing cup that I used still had some epoxy in it that wasn't hard... its still gooey (around 6pm). It's been around 21 hours and it isn't rockhard. It sounds like I didn't mix equal amounts, although I'm pretty darn sure that I did ... is that the case? This is the first time I've used Devcon epoxy, but what I hear from friends its really good. Is there anything I can do... add more hardener and try again or does it just take much longer to set?

Thanks for the help!
