So how much of this stuff did he use in addition to the Dynamat that was already used? Isn't there also a point to where this becomes a substantial weight issue?

Noland, you know both of us need special dampening as we hear things others dont

BlackHarleyMan

VERY True!........., so given all of the choices and the test results what's the BEST answer, also taking in consideration of weight.

Noland

P.S. LT4 I SWEAR I don't mean to hijack this thread, so please don't take it like that, I just need to know what choices are you seriously considering here because I may follow suite!

I actually think this is the best way to do it .this stuff is very light compared to the other stuff and i actually think it works better.for me the noise was not the biggest problem it was the heat that use to come up through the floor boards but after the install i was very surprised at the amount of noise and heat it blocked out .just so everyone knows that heavy sound deadener that has foil on one side and the heavy black asphalt stuff on the other side like fatmat,tsunami,dynamat will dry out and crumble like a cookie in a few years .you can go to home depot and get the stuff that has foil on both sides .the total weight you will ad to your car will be about 10-15lbs only compared to the 35-45 lbs of the others.

No prob I've actually been working (lol) in vegas, and just got back, so I haven't decided anything yet....too many choices

I ordered some dynamat extreme for my doors, maybe enough for rear, or I will do my door and rear carpet, as no passenger ever reall cares to ride with me. Besides, my door has NO insulation at all right now. So, it should be a difference. Will know by this weekend. I may get a decibel meter and test before and after.

I wasn't concerned with weight as I'm not planning on racing my car. I'm more concerned with interior sound. MY B&B setup is pretty loud and has a good deal of resonance, so much so that it's difficult to carry on a conversation. And I don't feel like dropping a grand for a Corsa.

One gallon of "QuietCar" weighs about 12 lbs., so one gallon when applied, cannot add more than 12 lbs. to your car. My restorer was able to get away with only using one gallon. He did both doors and the interior had Dynomat applied. He said the door sound after QuietCar application is night and day.

I would love to see pics of where he sprayed your doors. If I did it it would be a MESS!

I don't think my restorer took pictures of the QuietCar's application, but if you go to the following website, you'll see what he sprayed. The picture isn't of my car, but I'm sure this is what he did. The first link is QuietCar's home page, but the second is what the car door looks like before and after the application of "QuietCar." Take a look at the entire site; it is very interesting. And make sure you listen to the gong and drum symbol. You'll see what I mean if you go to the website.

As long as you cover what you don't want sprayed, you should be fine. The spray gun is an option and an expensive one at that. But I went for it because I figured that it would take half the time to apply QuietCar with the spray gun than if the restorer brushed it on by hand. I'm sure that I made the money back by not paying him to brush it on. And the spray gun will get into the nooks and crannies that a brush cannot reach.

With this post, you'd think that I was a QuietCar employee. It's just that my restorer was so impressed with the results of this product that I wanted to share his observations and comments.

Thanks. I see now what it should look like. Wagner power sprayer may work to.

The site recommends their spray gun because the liquid is very thick and their gun was designed for this particular liquid. If you already have a Wagner power sprayer, I'd try it first. Why buy their gun if you don't have to? But remember, if you are going to try your Wagner, make sure you thoroughly clean it as soon as you are finished spraying. Their site says that the liquid dries pretty quickly and you don't want to ruin your spray gun. You can always buy their gun if it doesn't work. But if it does, you save $50.

The precut system is made by Crazy Cowboy, a forum member, and sold by Exotic Muscle. Not bad looking, I was going to install one in my car along w/ everything else, but decided it was too much. The pieces do require a lot of triming.

Noland, I used about one whole roll Of the Raamat, weight is about 25 lbs. The foam was about 30 lbs, I would guess.

Many people sell this type of deadener, Second Skin has a very good product called Sludge, and remember, you can also use a roller to apply this stuff.

I bought a few sheets off of ebay and installed it , one door so far. WOW, that door has never been this quite. I am a believer in Dynamat Extreme. I am sure all of these products work very well.
I am very happy, and it was like 28 bucks for enough to do 2 doors.
Does anyone know square footage needed for entire Vette.
Also, do you think this stuff can cancel out the drone of allot of our C4 exhaust systems cause?

That's great! I decided to hold off and wait to do mine. I'm busy doing/planning "other" stuff with the car right now
I'm not sure, sorry.
I'm hoping that it'll help some...probably not much though.
