QuietCoat Sound Dampening
Okay, so am I missing anything about the "other" forum? I can't post the results here yet because the pics uploading doesn't work and I can't seem to find where I can upload pics to on the "other" forum? Any help with this?
Thanks.
Thanks.

THE RESULS ARE IN!!
Thanks Joel. I just figured out the nopsitons.com thing and posted the results of the project under this link:
http://www.nopistons.com/forums/inde...ic=43848&st=0&
Overall, I acheived a 13 dBa reduction in sound from the project. The car is much, much quieter and I'm extremely pleased with the way it turned out. Quiet Car works as promoted!
Once the pics capability is back up on this forum, I'll move the results here.

Probably 40 lbs based on the number of gallons I used. However, I removed my spare tire in the process so the net net shouldn't be that much.
And, yes, I was pretty surprised with the large amount of the reduction also. The Quiet Coat (now Car) guys were confident, however, that I would acheive these results.

P.S. I can actually drive the car now without hearing the roar of my friggin Thermal exhaust system! This is going to be the first thing taken off my car as I convert over to a 20B.
It's a very good product that delivers on its promises. The Quiet Car guys are pretty cool to work with also. When I ran into problems with phase two of the project, they had great advice and even sent extra material and spray guns at no additional cost.
It's nice when you can deal with a product and company that over delivers.

Hey David thanks for the tutorial and documentation, always knew I would be doing this some day.
So the big question is, how many gallons did you use to do a 3 coating job? You never actually mentioned it unless I missed it going through the thread twice.
And I also could not find a weight per gallon spec on the material either, so I couldn’t do the math on this statement.
do you have weight per gallon spec?
Any noticeable smell or odor associated with the material?
Any advice from your experience with the product or retrospective changes you would have made?
Also can you repost the pics to complete the thread, as the NP link seems to be broken.

ANSWER: I used about 5 gallons for the entire project.
And I also could not find a weight per gallon spec on the material either, so I couldn’t do the math on this statement.
ANSWER: No idea how much it weighs per gallon as I didn't wiegh it. My suggestion is to email the Quiet Car guys and ask.
do you have weight per gallon spec?
ANSWER: See above.
Any noticeable smell or odor associated with the material?
ANSWER: When you first apply the material yes, after it dries, no. The product has a chemically paint smell when first applied. It's not very bad though, not like some other products that knock you off the chair. Once the material dries, no odor exists.
Any advice from your experience with the product or retrospective changes you would have made?
ANSWER: First, I would do this again as the product really deadens the sound inside the car. I don't know why the sound mat materials remain so popular as this stuff works way better and weighs less.
Prior to the project, the car would drone at about 60 MPH and I would come home with a ringing in my ears. Not good. Now you can actually carry on a conversation in the car. No more ringing.
My advice to those that wish to use this is to start with the trunk area first - you get some bang for the buck here and it's a good place to learn how to paint on the product. You can mess up here and still cover the area back up with carpeting. Unlike paint, use thick coats and then let each coat dry before applying the next coat. Once you are completed, allow several days for the material to bond to the metal before measuring how well the product deadens sound. Most of my measurements were done the next day because I couldn't wait to see if the stuff worked.
After the trunk, do the inside of the doors (it's actuall pretty easy) and then do the body. You'll get best results if you remove the interior and paint the product to the inside of the car, including the firewall area. I didn't do this - couldn't see myself back then removing all the interior components. I would definately go this route if I had to do it again though. I used a sprayer to coat the underside of the car instead, including the transmission case (recommended by Quiet Car). This works okay and did definately help to deaden the sound but it's not pretty looking and it will peel off over time in areas that were greasy. I pressure washed the underside first but this still is not as good as doing the interior instead.
Do the inside of the hood? I did but am not sure I'd do this again. Don't know how much sound it eliminated and I still worry about the material trapping heat under the hood. This may be irrational but maybe not.
So, the end result is Quiet Car works well, weighs less than mat material, is easy to apply, and you'll achieve better results. Can't beat this in my book.

Project Pics: Phase 1 Trunk
Hi,
I was asked to post pics of the Quiet Car project again. Don't know why they disappeared but they did. You can read up on the product at http://www.quietcoat.com/. I also apologize for the small pics. Didn't really know how to reduce pics three years ago when I made the pictures.
Phase 1 pics:
Product (now called Quiet Car):
The trunk before and after:
Even got behind the rear lights:
And the trunk lip:

Project Pics: Phase 2 Hood and Doors
Hood after applying Quiet Coat:
As I stated earlier, I'm not sure I would do this again. I worry about the heat retention on the car. I would definately do the firewall though.
Doors before and after. I also did the insides of the plastic door pieces for sh*ts and grins:
It's hard to tell because of the size of the pics, but I brushed/painted the material on the insides of the doors also so I coated both sides of the doors. It's actually pretty easy to do as you use a paint brush to reach inside the door panel. Of course do this with the windows rolled up or you paint them instead.

Phase 3: Underbody and Wheel Wells
Here the pics get larger!
The car on a lift. I removed the wheels and prepped each wheel well. For optimum results, you should also remove the plastic wheel well linings. I didn't do this but might go back sometime as I think a lot of noise comes thru the wells.
I bought a spray gun attachment and a latex paint conditioner to ensure the Quiet Coat would flow well enough. I understand you no longer need the conditioner:
Wheel wells taped and material being sprayed on (kudos to my good buddy Mark shown in the pics for assisting with this):
Underside completed:
FYI - I also removed my rear speakers and painted the Quiet Coat material behind them.
That's basically it. No intimate knowledge needed for the project and huge reductions in noise for the car. It's actually quite easy to do. The most challenging part of the project was probably removing the black plastic "triangles" in the inside front of the doors (broke one popping it out), and the door panels and screws. What I suggest is you take pics of everything beforehand so you can see how to put it all back together.
Enjoy!

^No, the material bonds to the metal and eliminates vibration, the source for noise. So, you would need to remove the dynamat to use the product. I guess you could apply the material to the underside of your car but this might be overkill. Maybe to areas you haven't covered with the Dynamat? Firewall, etc?
Just as a point of interest, I received information back from quietcar.

What is the weight per gallon of this product, both wet and dry?
Approx 12lbs/gal and 8lbs/gal
Does this product have any smell associated with it wet and/or dry?
When wet like latex paint. None after dry.

Okay, so i used 5 gallons on the car, or 40 lbs. Good trade off for the sound improvement. Remember, mine is on the high end - I sprayed everything. The most bang for the buck was doing the doors.
david, this maybe a long shot but a couple years back 2- maybe 3,
did you manage to run into a Red Rx7 with a Really LOUD exaust,
with a young kid driving it?
only reason i ask is when i was leaving jaxsonville, i was so mad i didnt see any other FD's and as im leaving i ran into a black one, with a older gentleman driving it., im really wondering if it was you.
we ran into each other getting on I-95 cant remember the street name.
i think back then you were still on the stock twins,
and i just got my single t-78.

Fortunately it wasn't me, at least not that I can remember at my ripe old age of 45. It it was in the last 3 years, it's likely my car has not been here as it has been undergoing the 3 rotor conversion from hell.
