Any body out there know how to stop it...got 2 twelves and the trunk rattle like crazy...especialy the back part of trunk that is hollow.anyone have any ideas???

Use foam rubber pipe insulator to line around your trunk then slam it shut.

Dynamat Extreme works pretty well...

yup, mine rattles too. i have dynamat on its way!

Dynamat won't stop the real rattles.

A couple of dead bodies, just got to change em out every few days, ok, seriously, try Foam Fill, made by Red Devil. It's made for doors and such to help seal but you can use it on trunks and stuff too. My son did it to his Lebaron on it worked good!! It comes in different levels of expansion too.

coo thanks gonna use that foam spray an dynomat let u know how good it works

well, be careful when applying the foam spray. Don't apply too much because it expands and can cause some pretty nasty damage. I've heard horror stories about people warping their body panels and it bubbling out due to the extreme expansion of the foam.

just get the minimum expansion foam, mess with it from there
