For those that have replaced carpet...

[Green Monster]

Has anyone replaced the thin "tar-like" material that was installed under the carpet at the factory and was designed to absorb sound vibrations in the floorboards? I'm purchasing all the material to install new carpet and found this item on www.brotherstrucks.com. I see my 72 Blazer has the original "tar-like" material still installed but it is many pieces as it has cracked over the years. So I'm thinking of replacing the "tar-like" material with new "tar-like" material along with the installation of heat resistant carpet padding/insulation in the front and rear section of my Blazer.

Does anyone see benefit in installing the aforementioned "tar-like" material other than to restore the Blazer to original specs or should I just get rid or it.? The advertisement on Brothers Trucks website indicates the "tar-like" material absorbs moisture which could prevent rust. I'm a bit skeptical of that claim. Cars that are manufactured today do not have this material installed under the carpet anymore so I'm under the impression it serves little, if any, benefit.
