Then close my garage doors and fire up a propane heater to warm the room and help kick off the resin.
Please post pics of how you heat your garage to about 250 degrees for about 4 hours...that will be a tremendous feat if you don't set the house on fire.
If you are going to experiment - I would lean toward the UV curing because the resin won't kick until you turn the light on and cure it allowing you all the time you need to get it laid out properly.
But you also need to calculate a layup schedule with a full understanding of all of the components strengths and shortcomings. Last thing you want is a cracked hull.
