Hello,
I park my car everyday in an open parking where there is no assigned parking. I have been seeing my car doors having small scratches on the front and back doors, it looks like some one door dinged into my car. I cannot find who did this but its always a white residue seen on the scratch assuming its one white car who does this. The frustrating thing is there are about 4-5 white cars in the parking so cannot pin point who did it. Any suggestions how can I find this person who is doing this?
