Mix the resin thoroughly and run a little test batch to see what happens. If it cures properly, I wouldn't hesitate to use it on little, non-critical parts. I did that once and my test batch kicked off just fine, but when I laminated with it, the part didn't cure until I set it in the hot sun for several hours.

I was told the same by USComp.
MEK is critical obviously.
