Really sorry to hear tbat.
Just a month ago some punks went on a graffitti rampage here, some in my neighborhood. They tagged the entire side pf my wife's minivan with red paint. I called the police, filed a report, and cleaned it off myself.
Good news is they were caught that night, and charged with thousands in property damage. They tagged houses, vehicles, all kinds of crap.
Wow, was I mad...got it cleaned off with carb cleaner, microfiber towels, wd40, and a wax job. Lucky the paint was still gummy.
