Looking to improve the sound and eliminate some rattles in a car we own. Mainly in the trunk. I have been researching sound dampening matering that you can install yourself.......almost like wallpaper. Some of the mfg are Dynamat, Hushmat, Fatmat, etc.

I was wondering if anyone has any experience in installation and what (whose) material was best for this. It's not cheap so lookng for a little advice first.

What is somebody doing in the trunk?

not very helpful Mr. Cee Dog = )

dude, get a cargo net or a box with velcro attached at the bottom

if that fails then turn up the bass

and don't forget to tighten your spare and jack hold downs... better yet, take them out and see if the noise goes away...
 
I removed the entire interior in.my car and used cool-it by thermo tec. Much cheaper then dynomat. It worked great. I have two layers on the floor boards and three on the transmission hump. I am very happy with the results. I am doing the trunk this summer.

You can pick this stuff up from summit racing.

Thermo-Tec 14620 - Thermo-Tec Acoustical & Heat Control Mats - Overview - SummitRacing.com

Here is the start of mine.

I had dynamat in my old car, it solved a majority of the rattles but it's relatively expensive if you don't have a hook up. Not to mention it adds a lot of weight to your car. As mentioned before, try finding loose panels/spare tire or even sometimes the tail lights depending on the car before taking the plunge to spend that much, keep in mind its almost impossible to take out if you decide to later on, since it's basically tar with foil.
 
I would check out "eDead". I did some reasearch a while ago and found it a cheap alternative to the name brands like Dynamat. I believe Dynamat was 55mils vs eDead is 45mils but it's MUCH cheaper. I ordered mine on Amazon with free shipping.

Best of luck!

Not to throw fairlady under the bus here but make sure that you don't get a product that uses "Tar"!!! The products with Tar will give your ride a nasty odor, and can melt under high temps. If you check the product specifications, you'll see that the high end stuff all use a rubber or "Butyl" compound.

Just make sure you get something that says "BUTYL".
 
Couple things to remember when buying sound deadening material for any vehicle.

1. Do NOT use anything that is asphalt/tar based. Not only will it smell like tar in the summer time, but it will also not stick to any vertical surface.

2. When applying the sound deadening material, be sure that the surface you are applying it to is CLEAN, CLEAN, CLEAN! Using a mild to strong cleaner such as Optimum Power Clean is a great start to getting the panels prepped and ready for the sound deadening material.

I dug up a couple pictures of my car from a couple years ago. I used Second Skin Damplifier Pro. In terms of butyl based sound deadening products, it's about as good as they come. I gutted my interior a couple years ago and applied it over every metal panel and it's still holding strong with no signs of letting go. Not only did it drastically improve the midbass from my door speakers, but it also made the car much quieter on the highway.

i prefer a mix of dynamat xtreme and dynamat superlite. it depends on what and where on the vehicle, though.

there are a ton of companies out there that make competing stuff, but very rarely do they end up staying in the industry too long. i have never really figured out why, and i know dynamic control's business is completely based on such materials, for home, industry and automotive, so i stick with them, even though it is more expensive than the niche competitors.

useful tools are something like Nick mentioned, PowerClean, especially if it's an older vehicle and there is some accumulation. also, some sort of prep solvent product like Prep-All to clean all surfaces where the material will be applied, a sharp utility knife or shears, an old hair dryer and a small rubber roller like a wallpaper seam roller. you can also fab something up with a soft durometer wide long board wheel.
 
Glad to see this topic pop-up, as I was wondering on this earlier.

Nick or aznwhip - With regards to the Damplifier Pro, is that site the best place to get it (direct)? There isn't a dealer within 100 miles of me.

My truck is a 1971 GMC with an all steel cab, a hot engine and loud exhaust. When it sat in the garage most of the time, this is fun. When you drive it everyday, it is not so fun. :D

Might have to do it in phases for the expense.

I bought it directly from the manufacturer. :dblthumb2:
 
I've been wanting to do this for my G35 for a while but with so many options out there I was always skeptical. Every time I go for long trips I dread the noise. I might look into doing this for my next project on my car.

I didn't mean it in a literal sense, I used the term tar to describe how it's a PITA to remove if installed properly.
 
Second Skin or Sounddeadenershowdown are the only products I'd consider. Others are either too expensive (Dynamat), or worthless (edead). Sounddeadenershowdown has some excellent reading, and customer service is top notch. (and NO, I'm not affiliated with any of the above).

Noise? Isn't the noise heavenly? By noise I'm assuming you mean the sweet reving sounds of the engine tempered by that mean exhaust...

when I rev my car it sounds a little high pitched and whiney (from the inside at least)
