Sound proofing material?
all the stuff mentioned above are asphalt based and if you are in a warm climate city your car will smell, I'm in cali and recently installed raamat and ensolite, remember raamat(dynamat) is sound deadening not proofing you will help with vibrations but you will need ensolite to sound proof.
on my hondas I used to do a layer of aerosol "rubberized under coating" from advance auto, it would stink real bad for about a week, and good trick is if there's a spot where to pieces vibrate and its somewhere you don't see when the interior panels are in place you could "spray foam" the small gaps between those pieces, but make sure its out of direct sunlight as sunlight will melt the foam as it cures. Yeah its a bit ghetto but its cheap and highly effective.
Sound proofing and dynamat are two different things. Dynamat is meant to reduce vibrations and road noise. Sound proofing would require a closed cell foam to stop the noise.
Something like this:

But I used FatMat Extreme. Was about as thick as Dynamat, but made of a different material.
I did that before. It kinda worked, but it didn't. You can not get the spray coating to lay thick enough to add enough weight to the panel to effectively reduce it's resonant frequency.
Spray foam in tight areas: yes! I'm a big fan of that.

I don't think I even bothered to do it on the last honda, my brother is thinking about gutting the interior of his prelude and doing truck bed coating, don't know if that would be any better but it would be far cheaper then dynamat and he doesn't have a system so he doesn't need much. But it needs a good degrease before anything happens the previous owners ragged it out.

Sound deadening is what i would want proofing was not quite the word i meant. So it seems everyone recommends/uses dynamat i see they have a extreme version which i dont know is any better and i see eastwood sells their version of dynamat anyone use that?

I am kind of wanting to reduce road noise in my camaro too. You guys think four sq ft would be enought Dynamat to do the main part of the cabin (under the driver/passenger seats & floorboard)?
