…being a guy and coming out to get into your car first thing in the morning and seeing this?
Frankly, I have to hand it to the wronged party here: it’s inventive. I think you can probably have the car painted. It might even be cheaper than repairing it after it was keyed.
Just imagine driving to work. It’s such a perfect revenge because everyone would know after one glance that the guy was a dirt bag.
Frankly, I’d never do something like this only because I was too afraid of authority. I might want to, however. (With every fiber of my being.) The guy would definitely be toast, though.
