Will epoxy cure at temperatures as low as 40 F.

Yes. The general rule is that the curing time doubles for each 18F/10C. a
bigger problem is moisture. The hardener likes to react with water instead
of epoxy.

When my friend and I built a glued lapstrake dinghy in the winter, it was
often freezing. We hung 75 watt lightbulbs between the moulds and covered
the hull with a thin foam/aluminum blanket when curing overnight. Most of
the time the epoxy was cured in the morning.
