whats good to use? i know ensolite is a good seller for sound deadening and sound filter but i dont think it stops rattles

i was thinking of buying some dense foam from home depot and putting it on top of RAAMmat BXT in the doors/rear deck

thoughts? ideas?

Most of the time rattles are caused by interior panels not fully being secured. Besure not to break any of the plastic clips, if you do get replacements. The rear deck is a trouble area when it comes to rattles.
