What a nice day out and I am preparing to begin construction of my Coho. I have been putting it off for so long.....

Anyway, I have 2 jugs of System 3 epoxy, 1 of 'fast' hardener, and one of 'regular' hardener. The epoxy and the fast hardener are the same light clear yellow color, and are clearly labeled. The 'normal' hardener is not labeled, but by process of elimination I do know which one it is. However, it is pretty dark, like a dark honey. I don't remember it being that color before. Am I OK or is there a problem here?
