I'm almost 16 and getting a pretty nice car soon (Nissan 370Z, Corvette,etc) and I was wondering on how do I prevent my car from being keyed?(Especially School) Please dont say I'm spoiled or anything like it. I'm not the type that gets into fights or anything but am afraid some people might get a little jealous. Is there a special alarm system that can prevent this or some liquid that would prevent it from getting keyed? I just dont want my first car being scratched. Thanks for all your help guys
