I live in what at times seems a ridiculously small house. In the interest of domestic tranquillity I'm thinking about moving my safe to the unheated garage. The garage does have a wood stove that I run often in the winter for ski tuning, gun work and auto repairs but the temps will drop to 0 F at times. My safe is equipped with a golden rod. Is this a good idea or am I at risk of rust?

Thanks
Michael
