After having the stock sound insullation removed, I don't like the rattley sound of the car, the loudness on the highway, the drone of the exhaust, etc... So, I'm thinking of dynamat, or some less expensive non-name brand equivalent. Just wondering who's done it and any suggestions or AAR comments you've got on your installation.

Also, how much weight is this likely to add. What did it cost? (did you install yourself or pay?)

And as far as instillation goes, get a spray bottle and fill it with denatured alcohol and wipe everything down first, then apply the deadener. FatMat send me a wooden roller and razor knife with my roll.
 
Looks good. Thanks. Did you achieve what you were trying to with it? Is it pretty much the same as dynamat, only cheaper? People take this stuff out for the weight savings, but it looks like it's only 32 lbs for everything that ships. If that's enough for the cars, it should cost me 3 hundredths of second at a drag strip, but if it gets rid of drone, makes the stereo sound better, and reduces ambient noise levels, that is soooo worth adding the weight. Thanks again.
 
I did it in my Ranger to hide some rattles and whatnot. I have a pretty big system in my truck so deadener was a must haha. I mainly wanted less road noise though and I definitely have gotten rid of a lot of it. Although my truck was never REALLY loud before, it's pretty quiet now. To me, 30lbs is worth having a quiet ride. But I don't race..
 
I've used RAAMmat with great success and I had planned to used it again in addition to a layer of Ensolite on top and in key areas. However, I do like the info on the link you provided and the theory about only covering 25% of the area with CLD is really interesting. I appreciate that kind of honesty from someone. He could easily say that you need to cover everything (like everyone else does). I may look into the cost of some CLD tiles as well as the vinyl and closed cell foam barriers.
 
I'll bet I added 70 lbs to my car, and I only did from under the drivers seat back , and up the sides to the roof. like everybody said, it's simply a matter of peeling and sticking the stuff to a clean surface. It made a significant difference in sound deadening, and made the car seem more "tight" sonically. I didn't partition off the back seat, or do the trunk, so there is still sound infiltration from there.
Weight wasn't even a consideration for me, as it is a street car. I think a coupe needs more weight to make it ride nicer anyway.
 
I'm planning on doing this very soon, probably going with Fatmat, doing as much of the interior as i can manage to do. I'm not sure if i'll do the trunk or not but i do plan on blocking off behind the rear seats to isolate the interior as much as possible.
 
Based on what I've read, you want to go with a butyl, not an asphalt CLD. Fatmat was asphalt based, but what I read was a couple years old. If it still holds true, you're better off staying away from that stuff. It may be cheap, but apparently it does terribly in heat, and will stink up the car. At less than $3 per panel, and most people using 10-15 panels to deaden their car, it looks like you save money, weight, and time by going with the SDS stuff, or conversely you could buy Dynamat Extreme (not original dynamat) and cut it to do the same thing on the cheap. Something to consider. I can't give you a testimonial, but I'll let you know how it works out when it's done.

Not much truth to this. I've had my truck in 106* weather this summer and it didn't stink up the inside at all. Now, there any many places that are hotter than that but if it's over 100* outside, I'd think the last thing you'd be worried about is the smell of your sound deadener.
 
I used hushmat in my 88 and it is great the extra weight is worth the quiet and comfort. I had the same motor and trans in my 87 and it would get so hot I had to keep a little terry cloth towel in there to or I would burn my leg on the console. In the 88 it sounds like stock exhaust almost even with the t-tops out and the car is at least 10 to 15 degrees cooler on a hot day.

Cool. I'll take your word for it. Though, I still like the sounddeadenershowdown method of coving only 25% of the panels. At less than $3/panel, 15 panels is still only $45, which I think is enough for the whole car. Seems like the way to go to me. Maybe it's BS or hype, but others have testified to it.

Regarding the smell comments, I think people tend to knock other things to justify their own purchases to themselves, even if they haven't tried the other brand.

When it comes to covering only 25% of the panels, that's true. It just makes me feel better to cover everything LOL.

And with the smells, I've even used Peel N' Seal from Lowes and it's held up just fine in summer weather without smelling.
 
i have had the fatmat in my car for over a year now, it made a huge difference and i havent had a problem with it getting hot and deteriorating at all. I used less than 50 sq feet, there are some pics of it installed in my progress thread. I still have the factory stuff on the firewall and no deadening between the front of the seat mounting point and the firewall and its fine. I wouldnt hesitate to use it again.

I also read that deadener showdown site and while that dude knows his stuff, his methods seemed a little overkill to me, and since he is selling a product, i took his criticism of stuff he wasnt selling with a grain of salt
