Thanks for the support guys, just needed to vent as I definitely want to keep my cool. Pretty certain it wasn't road tar. It was pretty isolated to that one rear quarter area above the wheel well. I did note some road tar that was closer to the ground and it smeared when trying rub off and eventually it came off with some degreaser. But this fine stuff wouldn't budge. The alcohol swabs had navy blue residue on them leading me to believe it was ink. Luckily the pen they chose to use didn't scratch it.
Accidental little nicks and scrapes are although painfully acceptable with normal wear but purposeful damage is another thing. It initially bugged me enough to question if I wanted to be so afraid to drive and park this car anywhere. I worked hard and wanted this car for so long and it's mine and I'm pretty determined to drive it confidently and will be super selective where it gets parked.
