Hi. I want to replace the part that is on top of the rear bumper. I believe the part is there to protect the paint from being scratched taking things out of the trunk. I have no idea what the part is called. I own a black 08 Cayenne base. Its the white strip on the top of the bumper. Anyone know what that part is called? Or how you would replace it? (I assume it pops off somehow. Mine looks disgusting.
