Stubborn stains on my painted plastic rocker panel

[sagdast]

I just got my brand new BMW Z4 M back from Nick Alexander BMW for engine repair (a rock on the road managed to lift itself into my accessory drive and bust my steering pump, alternator, pulleys, tensioners, and crankshaft counterbalance, resulting in a $5500 repair, that was covered by my comprehensive coverage).

Upon inspecting the body, I noticed a few stains that I could have sworn were grease stains, from a shop towel, but after bringing my baby home, I tried using soap, then toothpaste, then RainX bug/tar removal spray, and finally rubbing with Meguire's Car Polish to no avail. The stains might have gotten fainter, but that might be psychological from all the rubbing that I did. Could this be some kind of corrosive lubricant???

I called my service advisor at Nick Alexander, and he asked me to bring the car back to see if they can get the stains out. I really don't want to have to leave my car in the shop again. Any ideas as to how this could have happened and what I can do about it?

Not sure what you mean, could you please elaborate?

I think what he means is actually put pb on the moulding and wipe off, or try a dressing, and at last resort paint or dye them.

I could not access your link, but I would try DG 481 (wax eraser) followed by black wow or black again.
