Applying a polyurethane top coat to a wood finish in a cold winter garage turns out to be a bad idea.
In my case, each '2 hour fast-dry' coat took over 10 hours to dry in 45'F weather. And worse, the stuff won't flow smoothly or disolve itself properly, leaving lot's of little polyurethane boogers all over the finish.
Next time I might try to make a wipe-on varnish by thinning the polyurethane with turpentine or naptha, but I suppose wood finishing is better suited for warmer weather.
