Doing an SQ build in the GTP and was looking for some input on dampening material. I have used Dynamat numerous times and was wondering if anyone has used the other various brands out. Thanks for the input.

I have used rammat and I love it, coupled with the ensolite they offered its a good material for a very good price.

I have also used second skin products, they are awesome but price is pretty high.

don't forget about undercoating the bottom of the vehicle with a heavy tar like substance, good if you ever travel on gravel roads, keeps the noise of rocks hitting the metal to a bare minimum

I have heard good things about rammat. You ever used Fatmat? Seems alot of ppl are starting to use this.

Dynamat Extreme. Roughly 200 lbs. for SQL and SPL comps.

I used Dynamat extreme in me spl truck and sql honda but was looking for something a little less exspensive this time around. I might do the floor with fatmat and then the key areas with dynamat extreme.

I know a few guys who have used peel and seal (roofing stuff) and it works pretty well, they usually step up to the real stuff later after they get some sponsorships though

I tried some of that once. worked ok but fell of few months later. We eventually used 3M spray to help it hold. As far as sponsorships I want to stay in stock class so thats not an option unfortunately.

Hey folks,
Here's another vote for RaamAudio's RaamMat. Not only for a killer product, but also for A+ support. If the market's anything like it was a couple years ago, the price/performance ratio cannot be beat by the competitors.

This is my first post on this forum, btw - I've had an '06 GP for less than a week.
