There are alot of rattles in the trunk. There is the trunklid itself, which is fixed using the above method. There is the rear dashboard which rattles too. Go buy 1" thick foam and put it between the carpeted piece and the steel part of the rear dashboard. That fixed it for me. Some people have been buying hard styrofoam (for insulating houses) at home depot and covering the floor of the trunk. I'm going to do this on my days off next week. It's cheap an apparently has good results.
