in all honesty, people are going to say ohh your a keyboard warrior etc.. but if i caught someone keying my car, i would happily go knock on their door, confront them tell them you saw them do it, give them a chance to apologise and pay, if not i would punch them square in the face then go kick a few panels on their car. I live in east london, you have to stand your ground otherwise it will happen more and more with people thinking they can get away with it.
