I have a large (36x50) finished garage, with a furnace. I normally keep it set @ 35 F. At Christmas time, I have a large family dinner, with lots of children. So I heat and clean the garage up for the dinner.

I am a bit careful on heating the garage up. I make sure the Cobra is not placed in an air stream. I heat it up 10 deg and let it stay there a couple hours then step up another 10 until I get to the desired temp. I have to clean anyway and prefer to work in the cooler temp.

I have heard of people cracking paint on Corvettes by cranking a furnace up full blast on a cold day. Don't know if it is true, but thermal expansion is real. Too fast may be a problem.
