Hello dear elk! I recently saw something super great in a channel on German television! You buy a fat lipstick for the cold season in the supermarket. If it is possible, it should be nice and wide for big lips. Now it is still cremated in the parking lot of the super brand, all the rubbers of the doors and rams of the V40 with this lipstick. Very important, it must be in the day and in the night plus degrees, otherwise the lipstick does not help! If it gets cold again, so below zero you get all doors open. Is a great thing and saves money. When the door seals tear, it costs really money. Nice greetings from DOS6.2
