Thanks for the help here guys, I rented a heater and got the garage up to a toasty 82/84 degrees and went to work on it yesterday morning using a scotch bright pad, after it was cleaned and lightly scuffed I started mixing, used the full gallon and applied it with both a foam roller and a rubber squeegie, when I went to bed last night it was (very slightly) tacky to the touch, this morning its hard, I rented the heater for 24 hrs. so I'll let it bake for a couple more before I have to return it and let the boat sit for a couple more days, should be in the water Friday morning \:D thanks again for the input guys.
