I'll keep everyone posted on how it works to quiet down my interior. BTW I ordered 10 of those sheets to do the interior.

polymeric mastic......Mmmmmmmmmmm!

What was the cost for 10 sheets? I need to call up McMaster Carr soon, and get some of that good stuff too... /forums/images/graemlins/thumb.gif

ps. Use a heat gun and a small roller if you can find/borrow them. It will make the adhesion more complete, and give you the best damping results....
 
Sweet! That would have been over $500 for Dynamat brand!!!


That would have been a REAL /forums/images/graemlins/eek.gif
 
$500 for real dynamat /forums/images/graemlins/eek.gif /forums/images/graemlins/eek.gif

I started putting it in today. Im trying to get the bottom layer to cover all the metal on the floor, then im going to lay down the big sheets in one big piece for the second layer.

COOL!!!!

At the very least, stagger the seams so they don't all line up on each other. Using a single big sheet is cool, but that can be real pain to work with.

Looks good dude! /forums/images/graemlins/thumb.gif
 
Any updates? New pics?....Any road tests for improved noise suppression???

I'm only asking because I need to order mine soon if I'm going to make it to Frank Raines by the end of this month!!!

I got the front done in one layer so far, I have noticed that the music sounds a lot clearer than before but it has only quieted down the inside a little bit more than with no carpet. I may start installing the second layer in the front as soon as it quits raining. Ill get some pics too.
 
Alright I got the second layer installed and went for a little test around the block the truck seems A LOT quieter inside, Ill know for sure on my way to school in the morning if it is indeed quieter.
 
More layers....more layers!!!! /forums/images/graemlins/thumb.gif

Heh heh heh...
 
How come no one ever goes to the roofing supply store and picks up a roll of Grace (or any other brand, for that matter) of Ice and Water shield? You get a HUGE friggin roll for $90.00, enough to do multiple blazers. 225 square foot roll huge. Screw Dynamat.
 
That is what I did (Peel & Seal) in my s10

It works good and is only 1 layer.
I think I'll put on one more and finish doing the floor, firewall, and doors.
 
Do you have any specs on that product or a website?

I'd be concerned about it's temperature range (especially on the high end!) since it's going to be against the trans tunnel, etc.

It would be nice to know it's other specs too....but a website might be all I need to get that....
 
I've looked at the roofing membrane at Home Depot and wondered about the specs as well. My main concern was about the adhesive. Will it hold on to the inside of a door that's painted black on the outside, when the sun is beating on that door on a 100 degree day? I'll bet that the temp of the sheet metal is well over 150 degrees then. It would suck to go through all the trouble of installing that stuff, only to have it peel off and jam up the window mechanisms. /forums/images/graemlins/frown.gif
 
You owe us an update on the sound deadening installation and results...... /forums/images/graemlins/thumb.gif
 
Ok, I got the front portion of the mastic in. I put it on double thick. Right off the bat I noticed that it was quietier inside. The main plus I noticed was the increase in sound quality with my crappy speakers in the doors. I had a lot more mid bass that was crisper and faster than before. Ive been lazy these last few weeks and havent got my carpet in with the sound deadner attatched to that. Im sure that will also drown out a lot of the current road noise I have. I also need to get some time to throw the mastic in the back and redo the carpet back there. I will most likely start all of this when I get my truck back from the body shop next week. All in all I do recommend the mastic. It has a lot of bang for the buck, a lot more than new speakers would.

Ok Im done talking now, I sound like a 14 year old girl. /forums/images/graemlins/rotfl.gif
 
McMaster Carr polymeric mastic part# 9709t19. 32"x54" sheets,$14.62 each.temp.range-30 to +300 farenheit.
 
Black roof, hot day
Black door, hot day
Seems the same to me.n Plus the door is a vertical plane and the roof is a horizontal plane (i.e. holds more heat).

plus the vehicle usually doesn't have a large crawl space/attic building and holding BTU's

The only thing I would be worried about is the "squishy" factor as it heats up. It might not melt, but does it get "gooey"?
