For your sake, I hope you are wrong.
I would think the reports would have cooled plenty by the time they fell to the X. dunno.
Anyway, first thing i would do is go to your local (autozone?) and get Meguairs Paint cleaner and get a clay bar. (both should be with the car wash/wax stuff)
Read the instructions on both, then start with the clay and finish up by rubbing on the cleaner. You should re-wax after that, too.
Hopefully that would do it. Dont skimp out, spend about 20 minutes claying the hood, and another 10 or so with the cleaner. If the marks are still there, you need someting more abraisive like ScratchX, or take it to a detailer who can use a machine to buff it out.
