I haven't tried the minwax but with Enduro I have not incountered any problems like that. Is your shop on the cold side? that could do it, I think if you look at the can it should give optimum temps for finishing with it.
What temp. was your shop when you applied it? That can affect curing times, etc.... I've used that product myself, and have had good results with it. You just have to be patient when applying it....almost just "misting" it - several times.
