Auto body repair & detailing: scratches from wheelchair, sand paper, scratches

Question
I just bought a new car. I'm also in a wheelchair and have to break down my wheelchair after I get in the driver's seat. Pulling my wheelchair so close to the car puts scratches right below the door opening. Do you know of anything I can put there to cushion and stop the scratching?  

Answer
Debbie i have used some of the tape from the skate board shop,it comes in all colors and sizes, it is sticky like a stickers but the other side kind of looks like sand paper,you can cut it to fit the bottom rocker they even have some that are clear.that is the only thing i have ever used and I'm not sure if any one makes a better product.
