In winter even with my worklights the resin was really slow to go off so I purchased a gas patio heater and made a smaller enclosure in the shed out of poly tarp. I did the Nacra keels this week in direct sunlight and it went off too quick. Is it practical to heat from the inside of the hulls to say 18 degrees and then epoxy with the lights giving some lift in external temp or is this risking the integredy of the hulls.
