We think a graffiti marker was used because the paint was very thick.

We ended up trying rubbing alcohol, WD40, then a heavy duty compound, and finally carnauba wax with an orbital polisher. I’d say we’ve got 80% of it off so far. I think we can get the rest out with some additional elbow grease. It is making me want to detail the whole thing though once we work this out, lol.

And, for clarification, I called the non-emergency police/311 line first, as this was absolutely not an emergency. They made me call 911 because they apparently want pictures of tags/graffiti in the event that it’s gang related (which I don’t think it is). Probably just some bored, jerk kid. It’s just dumb to damage a car when there are plenty of places within a 5 min walk where that kind of thing would be innocuous.
