Well, I was posesed to remove the rear bumper cover trim (the black piece) form my 07 GP and I noticed the high density foam impact, what ever it is called was not fixed in place. I could move it around and I thought that to be not correct. So I proceed to remove lights, cover and well, it just sit there held in place by the cover I guess. Well, me being me and had it apart I siliconed the foam into place. Now my question is is that normal? for that foam piece to just sit there? Anyway I used some old silicon (bronze oil pan gasket silicone, as I would not need that anymore lol) and i figure if it works then great if not then it would be as it was before.
