Silver Fox - the ding protector is something I designed a few years ago. I work in an office park where at any one time there is probably 100 empty spaces. There were 4 or 5 of us with nice cars that used to take two spots in a very hard to get in and out of part of our parking lot. We were told if we continued that practice our cars would be towed. Out of necessity I came up with a door protector. Its basically two swimming pool noodles tied together with elastic hooks on either end. The noodles are tied together with the decorative rope you get at Home Depot. My wife made a cover to go over it from a gray, cotton towel so you don't see the noodles. The whole thing attaches to the wheel wells and prevents any door from getting near the side of the car. You can put on and off with one hand and they have withstood a 60 mph thunderstorm gust.
The first set I made were out of styrofoam but I found after using them for awhile they started to crumble. They did the job but were too messy to carry in the car. The noodle version is flexible and stows nicely in the rear compartment or in the passenger side foot well. Laugh if you must but I have no dings nor do I worry about them much any more.
