The windows on my truck are constantly frozen shut! Winter in MN sucks! I get them freed up and then drive around and they get warm... as soon as the truck sits and gets cold again they are once again frozen solid. Is there anything you can put on the gaskets to keep them from freezing to the glass? I'm thinking maybe Rain-X? I don't want to use WD-40 or anything oily because it will make a mess. Any ideas?
