so...i got this cf trunk. it rattles like crazy. suggestions on dampening it?
i was going to use 'great stuff' foam inside it and then dampen it...any other ideas?

 

i used the most common product....dynamat, in the bed of my s10, and also inside the cab. That stuff definatly works great, but its very expensive. Id reccomend trying to find an off brand of dynamat, just make sures its the same thinkness and you will be alright.

 

Edead works wonders. Lightweight and not expensive.
