More than likely, your Mustang shares the garage space with another vehicle, perhaps one driven by your spouse who may be oblivious to your repulsion to door-dings. A new product called the DoorPal could be the answer to your prayers. An inflatable protection panel, the DoorPal can be suspended from a garage ceiling using a proprietary safety release or attached to a wall where car doors are most likely to be damaged. Measuring approximately 100x34x4.5 inches when inflated, the DoorPal is designed to protect cars side by side, regardless of height, and it's transparent. It's currently available online at www.doorpal.com.
