^ That is defense in depth, and quite possibly the best way to use bedliner. (EDIT) The bedliner is similar in its performance to a thicker layer of steel and does have some significant advantages though without the other items Defro used its benefits would have been limited.

There shouldn’t be any off gassing once fully cured (most are epoxy based) since they are high solid (many claim 100% with no VOC).

I found a roll of 3/4inch thich felt matting, cut out what I needed to do the entire floor/firewall/trunk. That was cheap quick and easy and did the trick to boot.

the only problem ive seen and smelled with the felt is if it gets wet, it molds and stanks

would go with the cascade but i cant justify spending 140 US for a sheet... and id probably need 2-3...

is it that much of increase in performance if i used bedliner then 2 layers of regular deadening vs just the 2 layers of deadening?

also... what do you guys recommend for the roof? and is it worth taking the headliner off for?

thanks

I would use 1 layer of mat, and then do 1 layer of a product such as BQuiet Lcomp. The roof is a huge oppurtunity to deaden, on most cars it is the largest flattest panel, which makes it among the weakest, and best candidates for mass loading (mat type) damping.
