stick on side trim removal ?

I am interested as well. I removed mine and got all the adhesive off, but I have shadow lines on either side of where the rubber was. This is the best picture I have of it. Car is in original paint, but may have had some touch ups over the years, so it could be paint build up, or it could be old petrified adhesive. I thought about trying fine sandpaper, but am afraid I will make it worse. What is an eraser wheel?
