I think that I am going to put a little can of that in my hunting jacket for next year. I used to keep a little can in my jacket pocket during the Winter season. My friend and I were once ice fishing and when we left the lake and walked to shore, I guess our hands got too cold, we could not get the key in to turn the lock. I thought we might have to bust the window or freeze. When we finally got it open I carried one from then on. I believe it does contain some type of lube to prevent future freezing up. In MN just just carrying something from the warm house to outside can cause problems with stuff freezing up. You brought up a good point to avoid future headaches.
