The speed of chemical reactions increases with temperature. If it's so
cold in your garage that the solution freezes, you won't see much
happen. Naturally the process will take longer at a lower temperature.
No noxious fumes are given off that I've noticed. It's a good idea to
agitate and turn the parts from time to time to get rid of bubbles and
accumulated byproducts. Also, be sure to thoroughly degrease the parts
first because grease acts as a mask.
