Hello all. I'm enjoying this site and all the info, great stuff. I was recently given a gallon of epoxy resin but not the hardener. I know that it requires an amine hardener and I will experiment to find the correct ratio. Question is, where can I buy just the hardener and not a kit? I would prefer a local pickup /big box store type of scenario. I live in B'ham area if that helps. Thanx.
