Since I had all of the interior out (except seat and floor carpet) I thought I would Dynamat the car before putting everything back in...
Supplies:
$45.00 for 12sq feet of 3M 'Sound Deadening Panels'
$70.00 for 12sq feet of Dynamat Extreme door kit
$6.00 for wooden Dynamat roller that broke after applying just a little torque. Damn cheap roller.
It was about 59 degrees. I wish it was warmer, bcz I think the material would be a little more maleable.
Those 3M panels were awesome! They are thicker than the DynExtreme and remind of the heat shields you see on the space shuttle. I put those on the rear firewall from edge of floor to the back glass, including the little ledge. That took about 10sq feet and they were very easy to cut and made a virtually seamless install. It looks like tile. I took the FORM out for a run and noticed a much more distinctly muted engine bay and exhaust noise. I will miss the rumble, but not the road noise.
Return and put the Extreme on the roof from lip of front glass all the way to the rear. That took about 11sq feet. Observations about the DynExtreme:
1)Much stickier (tackier) than original Dynamat.
2)Hope the foil backing will act like an insulator in Texas heat. Any opinions pls reply.
3)Though more expensive, it is supposed to be better at dampening.
I used the scraps to cover about 50% of each door and some of the pillars. Since I ran out, I bought another 4sq of Extreme for $30.00. This was supposedly discounted! Dang that stuff is expensive! (and I did not want to wait for mail order) I really only needed about 2 more feet, but I knew that if I didn't buy and install the remainder, that it would eat at me knowing I had missed a few sq inches here and there. I will let me sleep better at night knowing that I didn't half-a$$ it. My darling wife still does not understand. "But honey... I NEED the additional Dynamat..."
PITA to mold that stuff down in those little shallow ridges and dips all over the car. Why are those there anyway? What's wrong with straight metal?
A new road test shows very nice improvement. At 80mph, still with no interior... I could talk to the passenger without having to raise my voice. It was very pleasant. Big sound upgrades coming in future months, so doing the mat now will save me some time down the road.
Total cost? $161.00 (inc tax and cheap roller)
Total sq ft for total roof & back & doors? 26.5
Worth it? Hell yeah... especially if your going to add big sound.
Warning! If you want weight reduction... DO NOT Dyna your car! 6sq ft of the 3M stuff weighed as much as the 12sq feet of the Extreme. I liked the results, but I probably added 25-30 lbs of dead weight to the car.
Any other Dynamat experiences out there?
