? about DYNAMAT

[blackbeast]

here's what i did about 2 years ago when i redid the interior on my S-10 blazer. Imagine a box on wheels vibrating with a 350 and 2.5 dual dynomax mufflers.

I too couldn't afford, and didn't want to pay for dynamat, way too expensive, and i knew there had to be a better alternative.
anyways, b-quiet used to offer a roll on plastic type deadner that seemed to satisfy vibration dampening. i rolled on about 2 coats of that and then added insulating foam with a aluminum heat liner from i believe Jc Whitney of all places ( i think it was 3/8 in thick) I also added another layer of factory sound deadning from a donor blazer and then new carpet. Since I had the dash out, i used the B-quiet rollon stuff, and a layer of dynamat b/c there was no room for anything else.



The difference was quite amazing, and this thing is dead quite cruising down the freeway 70mph, 1,100 RPM. I was told by a sound-guru friend that coating the cieling would also add a great deal to vibration dampening but the pain of pulling down the headliner again stopped me from doing that.

summary:
I spent around $70-90 and was able to significantly reduce sound (especially exhaust drone) on and S-10 blazer, which i would think would be much more difficult than the average muscle car.
