These two things combined eliminated all squeaks / rattles from the rear of my sedan.
Also did this this weekend, but im having problems with the lower piece of the panel below that is closest to the windshield not staying "clipped" in place. I used the quotations, because all i can see are two little notches that i guess are supposed to hold it in?? To clarify what im talking about, its the section in the upper right corner of this photo.
