My Ride: '06 530xi
I finished waxing up my car today, and went to feel my hours of hard work. Felt the bonnet, and it was like glass 
Then comes the bad part....
I find LOTS of small rust spots where my trunk meets the rear bumper! Upon closer inspection, the rust spots extended across the bumper, and around onto the fenders and top portion of all the doors!!! It's as if somebody took a sewing needle and poked the paint a few hundred times! They are very hard to see if you don't look for them, but once you do see them, your eyes catch onto all of them. All along the doors it's more of a black spot, with some rust mixed in.
EDIT: Markymark is correct, it is road tar. I used an exacto knife to carefully scrape it, and yes it did come off. I'm leaving the pictures up so others can see.

I suspect that is road tar, plastic parts like a bumper shouldn't rust.
Try a tar remover (Autoglym makes one). I have some similar looking spots on my rear bumper too

See post #1 for edit.
And will clay bar remove it?

Clay will remove it. Better yet, use plain old mineral spirits. I learned this trick workingin a detail shop many years ago. It will not harm your paint and will remove the tar much quicker and with less work than clay.

we took it off by Sonax Abrasive Paste. Great job.
