Aloha together, my girlfriend and I have heard what you can use as to prevent the case of high humidity and very low temperatures freeze the doors / trunk lid. There is also the problem that the gums are damaged. In our case it is a Polo 6N (Bj. 95, 5-door). The doors are frozen like the top of the roof at Fliess and near the hinge and in the tread bar. We have the deer applied at lunchtime (at -5 degrees) after we had made a tour to warm up the car (to thaw ^^). The rubber we then wiped dry and the flow is also used (microfibre cloth, plain old fat-free towel should also go. Then we applied the deer, it looks like a white "layer" not over the whole area. The tallow can also be seen as a greasy film, so easy shiny on the Gummies / Fliess. If this appearance is fading slowly, or if the weather forecast even lower temperatures are announced quietly resent again. The driver's door is always opened, and the two rear doors. Passenger door made from time to time problems and trunk lid rather rare problems. Since we had permanently about 20 degrees winter and rarely went down to -25 degrees, I intentionally in title only -20 degrees mentioned. If this winter prevail over -20 degrees over several days, so I'll note here that (I hope think of it :-)).
