emperorjj1 Posted May 11, 2010 Report Share Posted May 11, 2010 depends on how bad its rattling. may not be "fixable" get a bulk pack and start with the trunk and go from there. Quote J.

HHR Ed Posted May 11, 2010 Report Share Posted May 11, 2010 20 sq ft is more than enough for your trunk. Doing the doors and roof is an added bonus that should be a noticeable difference on performance. With the bass and full range music. Especially since the roof is the largest flat sheet of metal in the car.
