All,

What is the best material for the money to obtain to do the sound dampening materials in the car? Hush Mat? Dynamat? Acousti-shield?

Is it worth it purchasing the form fitting kits or to buy 2x2 squares or something like that?

Thanks,
Matt

IMO, the *best material for the money* is to do what the new car manufacturers did (or do)...  they use a similar decision criteria ... to be 'good enough', but not waste $$....

Sure does..  Its just like Dynamat; tar backed aluminum foil.  It reduces heat & road noise.  You can tell a difference when you shut the doors.  There is no echo or rattle.  Just solid.

Where did you pick that up? Lowes? Home Depot?

Lowes has it:
Peel & Stick

I had to check it out!  Looks like this winter's project.  Thanks, Cook_DW!  Grin  Grin  Grin

Anyone found any issues with these products trapping moisture/condensation? Especially in the roof area? I'm going to replace the original fibrous roof insulation, but don't want to put in something that could form a barrier to moisture, especially if it's not thick enough to act as an insulation layer.

Use a wooden roller when applying.  Helps to use a heat gun when rolling too..  As long as moisture isn't there when applied moisture will not get between it & the metal.  If you are that concerned about moisture then use an etching primer before applying.  I just wiped the surfaces down with xylene & let dry then applied..  I also let mine sit in the sun for several hrs to make sure the tar stuck to the metal.

Assuming it's rubber or tar based, it's effectiveness as a sound dampener has to be much more significant than it's thermal barrier capabilities.
