Are you sure its the bumber?

My car has rattles and its mostly the tail lights and the acutal hatch its self.

check to see if its the license plate too, sometimes that gives some rattle.

I used the expanding foam, I have 2 15's, and no rattle.

my bumper rattled terrible along with the tail lights and the hatch itself. No matter what you do to these cars I think theyu're always going to rattle. What i did is a took apart the whole back of the car. (basically the taillights and the piece that has camaro embosed on it). I bought some foam weather strips for house doors(get tehm anyplace like fleet farm or any hardware store). there are little plastic pins that help hold your bumper on. Pull them out...put the weatherstiping down under the bumper and then push them back through. I put weather striping behind the taillights then and anywhere else that could cause a rattle too, but the bumper itself was the worst for me and this helps Alot!
