Can't get this black stuff off the paint

[Timmmo57]

Not sure what this stuff is. It's collected on top of the spoiler. I thought it was either some type of mold or tree sap. I tried using 99% Isopropanol (rubbing alcohol) and Goo-Gone based on suggestions I read for removing tree samp. Didn't seem to loosen or dissolve the black stuff at all. Any ideas what it might be and how to remove it? I was going to try a clay bar next.

Have you tried bug & tar remover (the old Turtle Wax stuff)? Then soap and water?

what do you use to wash the car? might be time for paint correction.
