Review on Premium Car Door Protectors - 16ft Clear Edge Guards by Eytool, Ultimate U Shape Car Protection Door Edge Guard for Most Vehicles by Steve Hardy

I just bought a new car and wanted the door edges to be a little more secure (the doors are heavier than my old car). I usually open the car door fairly carefully, but this buffers a little more. It was very easy to install by simply cutting it to length and pulling out the little red plastic covering the sticky substance. I'm glad I read some of the reviews. There are no instructions. Place the sticky side on the inside of the door.
