    I matted mine too but still get the annoying rattles. Mine seems to be the back panel behind the bumper but can I hell get rid of it.
    Thats what we get for having big Bass!!
    Ive used the foam before on my Scooby's Spoiler, did the trick but got very messy, You dont realise how much that stuff expands!

    I asked my ICE installer and he says he'll do the Job for me, Shouldnt cost a great amount and after I heard the VXR they installed Ill be letting them do the business. All doors shut and hardly any Rattles at all.Increases the sound quality loads.

    havent been into audio in a long time but my thoughts at the time were that dynamat does two things:

    1. adds weight to the panel to stop buzzing etc
    2. actually absorb part of the soundwave to reduce the impact on the panel

    now the cheap gunk will only do 1. but given the cost savings that was enough for me. you can stick a couple of layers on any biggish panels.
