Yesterday NJ received snow and ice. Right after the storm I was able to heat the car and then open the front door without issue. This morning after an overnight freeze the driver's window didn't move down the way it normally would and the door didn't open very well at all. After using a small pvc card to try and loosen the window I was able to get the door to open. My question is how are people preventing the windows from literally freezing up? I know people have all kinds of ways to try and prevent frameless doors from sticking. From what I can find the most popular solutions seem to be: 1. Gummi Pflege Stick 2. Putting painters tape along where the trim and the window meet before a storm. 3. Using some kind of silicone along the base of the window to prevent sticking 4. Using some kind of a de-icing spray 5. A rubbing alcohol and water mixture 2 parts alcohol 1 part water in a spray bottle. While any of these seem like they're work I'm a little worried about the paint and the window seals treating them with alcohol doesn't seem like the best idea and the others seem like kind of a crap shoot. Does anyone have a better suggestion or something they've tried?
