Due to a growing family my hobby has been displaced to the external garage. Now I didn't really worry about any possible long term damage with it being stored out of the house until I awoke to see the garage roof covered in frost this morning, and entering and find it almost below zero inside.

Should I rethink how things are stored. Could things get damaged by the damp cold temperatures? Books, magazines, painted models?

Does anyone else have experience storing their hobby in a garage? Anyone loose anything this way?
