When I was in High School a guy I went to school with had something like that happen. His girlfriend wrote "BASTARD" on his car with something.There was some other "words" I can't post here also.Don't know what she used but it sorta burned/bleached into the paint...it washed off but you could still see it, like writing on a fogged up window...when it dries you can make it out. His parents sued her parents.:boxing:
