How do you remove these? I parked outside work the other day and got 2 scratches on the rear bumper. Then when I went outside today, I got another 2 scratches on the other side of the rear bumper. Can't believe how disrespectful some people are towards the property of others.They're not as deep as scratches from someone keying the car, but they're fairly deep. I read another post about using compound, is this in any way harmful to the car? And what other ways are there to remove scratches?
