Krispy:
What do you mean by "sheeting?" Did the epoxy not dry after a couple of days?
I'm using Famowood and it takes about 12 hours for it to set up; a day and a half for the plugs to be handleable. But when they do dry, the finish is beautiful!
In another application a few years ago (model airplane wings), I used some envirotex, thinned with acetone, but I didn't mix it thoroughly enough before adding the acetone. It just didn't dry. I ended up having to peel off the fiberglass, wash the surfaces with acetone, and start over. But the second batch, stirred with about 100 strokes of a tongue depresser before thinning, worked fine.
As a result of that experience, I mix epoxy until I think it's ready, and then mix it again.
