I have to park fairly closed to a concrete wall on the driver's side. I've already got one small ding just from opening the car door a tad too fast. I've looked at the small plastic guards you can get but I'd need two to cover for the front and rear doors. The wall is about 3 feet high and I was thinking about covering it with carpet reminant. I'd prefer to use closed cell foam, but can't find any large sheets. I'm wondering if anyone has any better suggestions.
