Wow i didnt think many people had the same prob that i did. i think i am going to redo the dynamat in my whole trunk and my doors and i will probabbaly spray the trunk also. hopefully this helps but i cant get to it soon i am saving up for the rest of my svt kit. what i am going to do real soon is take the whole back off behind the seats and insulate that. so it dosent rattle against my glass. i have two gloves back there and they look funny.
