Sound Dampening

[upscope757]

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 $$....

You are gonna think Im crazy but I used this and it is holding up great..  Plus I did the entire car for right at $100..  Roughly 5 rolls with do the floor, roof, doors, sail panel area & quarter areas..




Here is my 67.

Great idea! Does it hold out road heat well???

[cook_dw]

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.

You guys are awesome. Thanks!

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!

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.
