Sounds like I need to go in the business. I have used Lowe's "reflectrix" in some areas and was well pleased. It seems that they are many choices and they all have their claims. I would be interested in seeing some results of these roll out or spray on products compared side by side to good ole 1.5 inche foil backed fiberglass roll insulation. One product did compare theirs to fiberglass but it was only to 1/2 to 1" of the poor quality automotive type without the foil. The inside door area is always a problem and I can see where one of the spray on materials could help. I would probably put my money in something like James was talking about (or linked) with the glass microspheres in an acrylic suspension (acrylic latex exterior paint) and made on the garage work bench. I'm sure a $7.00 siphen feed hand heald sand blaster would spray it. Sure, all the When theres only a small percentage of improvment for several hundred dollars difference, to me, its not worth it.

 

I used FatMat

I found it to be mediocre at best. i double coated the floor, roof, firewall, trunk, and every other place i could find to put it. My car is really loud inside. It does seem to eliminate the rattles but the road noise and exhaust still come through like it wasnt even there.

I also used a spray on rubberised sound deadiner and undercoating before hand.

 

I didn't use any of the spray stuff, and I was able to fully cover the inside of my doors with the stick on stuff. With the 69 and up cars the access holes are big enough that you can slide a strip through the window area and put it on easily if the windows are already out of the car. With the earlier models I would imagine it being a lot more difficult...

with this pic you can see all that I covered, you can even see some of the stuff in the doors. I also did the trunk as well

 

Over the last 2 years I've been in cars with the thin roofing products (Ice&Water Shield being one of the more commonly known names), Dynamat, FatMat as well as cars with the original sound/heat products. In regards to sound the 2 Dynamat cars were noticeably quieter then stock. The 1 FatMat car I was in wasn't as quiet though it was better than the Ice&Water Shield cars which I really didn't notice any sound difference then from any V8 classic with good or replaced original sound dampening. In regards to heat the guys with the Dynamat said they could easily feel the difference in the cars and found the cabin quite a bit cooler after the install. The guy with the FatMat said that he hadn't noticed much difference at all. As for the Ice&Water Shield products I've been told by the owners everything from not so much to huge temperature difference so take that how ever you'd like.

After a lot of online reading, some phone calls, talking to car owners of various types of product and listening to a number of their cars I made my purchase.

Second Skin won out over the other products though it is not cheap, neither is the shipping. The wife says she wants the big V8 sound outside and yet be able to listen to her stereo, talk on the phone or with others inside the car without having to yell. She wants it quite inside. Its a daily driver, not a race car so we are after a comfortable, quiet ride. Weight is not an issue. I'll be doing a layered install meaning a number of different products. I've already used POR-15 on both the under chassis and the interior floors, firewall, inside doors, etc for rust protection with a good Epoxy primer.

My order included 160sqft Damplifier Pro, 2gal Firewall, 5gal Spectrum Sludge, 10 sheets Luxury Liner Pro, 4 sheets Heat Wave. Total shipping weight was 344lbs in 6 boxes! Most of it is for the wife's car however some will also be used on another car. They had a 25% off sale which helped greatly.

Will it work? I'm sure it will! Just how much? I'll find out next year. Was it a waste of cash? I'll let you know in the spring. Would I do this in MY car? Unlikely! Does the wife get what she wants.... Always!

 

I purchased sound deadner from Harris Mustang in Charlotte. Its black on one side and light (uncoated) on the other. Reminds me of thick tar paper. Black side goes down. It comes in sections and is generic fit for 65 to 73 so I'm going to have to do some trimming and taping. Started laying it out tonight. I also put down 2 thick coats of rustoleum primer and 2 coats of rustoleum paint after repairing floors.

Question; do I still put down carpet pad (that came with carpet) over the top of deadner?

 

I know this thread is old but atleast its on topic with my question and carries some background info. Im leaning towards second skin, but how much do you think it will take to cover my mustang? 40 sq. feet? 80 Sq. feet?

I used this http://www.lobucrod.com/

I seriously was so surprised that it actually worked keep the heat from the transmission and made my car so much more quite inside





only cost me 70 bucks too

 

I wanted to do the Secondskin stuff in my 69 Fastback. I even got an email back.

Here is the response.

Hello



Thanks for your interest in Second Skin!


We have a ton of customers with your same Mustang, so we are very familiar with what products to use, and how much of each you will need, in order to accomplish the goals you listed in your email.



Since the majority of unwanted noise in car is structure borne, your base foundation will be a solid vibration damping system. We sell two types, that when used togther, provide better sound deadening results than any single material could hope for. We sell peel and stick mats as well as acoustical coatings, both of which will kill structure borne noise.



After you address the sturcture bonre noise the next step is to address the airborne noise.

See, it is impossible for one product to take care of structure borne noise, air borne noise and heat. This is why we sell such a wide variety of products. There is no "one size fits all" product, so we have a proven sound deadening system to get the most bang for your buck.



Our system looks something like this:



-Damplifier or Damplifier Pro (depending on your budget)

-Spectrum, our noise and vibration coating. (interior and exterior coating)

-Luxury Liner Pro (optional but recommended)



The Damplifier or Damplifier Pro will go inside the vehicle on all the sheet metal panels, under the carpet, behind the upholstery, in the trunk and on the ceiling. Everywhere that is hidden with upholstery should get a layer of Damplifier or Damplifier Pro. Some areas can even stand to get two layers. Remember that the larger and flatter the sheet metal is, the more it will resonate and transfer sound annoying noise. Adding a second layer of Vibration mat will not only increase the sound deadening results, but it will increase the results exponentially (the second layer nearly triples the results of the first layer).



You will need about 160 sq feet of Damplifier Pro to do the entire vehicle.

The more you do the better, but the more it costs.



The next product to address the structure borne noise is Spectrum, our vibration coating.

Use 1 gallon inside the vehicle in all the areas you are unable to reach with the Damplifier Pro, then apply 2 or 3 gallons on the underside of the floor pan and wheel wells. This will sandwich the floor between the two different vibration dampers and will completely destroy structure borne noise.

When this product dries, it becomes a hard, yet flexible black coating that will not only reduce noise, but will prevent against rust and corrosion. Because it is black, it is perfect for guys that are restoring classic vintage cars!

Your vehicle can use as little as 3 gallons or as much as 5 if you want to do an all out amazing job. Remember, the more you do the better the results will be.



Half of our customers stop right there and are more than happy with the level of noise reduction and thermal insulation they get. The other half of our customer are looking for tomb like silence take it to the next step, and start addressing the air bornse noise.



Our most popular product for reducing unwanted road noise, engine noise or exhaust drone is Luxury Liner Pro. This product will get applied directly on top of your final layer of Damplifier Pro inside the vehicle in all the areas that allow you to replace the factory carpet and upholstery comfortably. This last layer of Luxry Liner Pro will be the final nail in the sound deadening coffin that will insure you have a quiet, cool and more luxurious ride in your car.

Your vehicle can eat up about 6-10 sheets with no problem.

How much you use depends on how much you are willing to spend. This stuff is not cheap, but the results it will provide are incredible. There is no need to double up on this product.



You will also need 1 can of Spray adhesive for every 4 sheets of noise barriers and filters you buy. Damplifier and Damplifier Pro are both self adhesive and require nothing else to be properly installed.



The resutls you will get with a package like this is absolutly amazing!



To recap: My suggestion for your goals is:

160 sq feet Damplifier Pro - http://www.secondskinaudio.com/vibra...lifier-pro.php

3-5 gallons Spectrum - http://www.secondskinaudio.com/sound...r/spectrum.php

6-10 sheets Luxury Liner Pro - http://www.secondskinaudio.com/noise...-Liner-Pro.php



Feel free to call me with any questions:

800.679.8511



I will be happy to set aside some time to discuss your project further. If I don't answer, please leave a message. I will call you back!



I'm still considering going with them. Although now that I work at Best Buy part-time I can tell you I have bought Dynamat Extreme at my discount (which is VERY nice on Dynamat) and can say I have 160 sqft of it for a fraction of what the secondskin would cost.

Having said that with what I've read from the links (over a year ago) when I was looking for something for my classic truck I am still considering secondskin.

 

I did a single layer install of Damplifier Pro in our 67 last week. This covered the firewall, floors, roof, behind the dash, few areas inside the doors, complete trunk, wheelwells, quarter panels, trunk/cabin divider, rear package tray. This took about 110sq feet. I have another 50 feet left over to double up a few areas just haven't gotten back to it.

I bought the 5gal Spectrum though haven't sprayed it yet. I'll be putting a medium (2mm) spray inside on the floors / trunk divider and a thicker (4mm) multi spray on the under chassis, wheelwells & fenders. Inside the doors will get a medium spray over the damplifier. Whatever is leftover, if any, will go on the trunkside of the trunk divider. -- Its been bouncing between -5 and -30 up here for the last month and even with the propane heater & wood fire going its simply too damp and cold. Looking to spray in April.

I also bought 10 sheets Luxury Liner Pro and let me tell you.... Its HEAVY! We're talking about over 10 pounds per sheet (its comes rolled up) and a sheet is 9' long by about 2 feet wide. Now... I haven't installed it yet however I figure about 6 sheets should be more than enough for our classic stangs. I'll likely give 4 sheets to my father for his car.

The 4 sheets of Heat Wave I got are for 2 cars.. 2 for our stang and 2 for my father. These will cover the trany tunnel and inside firewall.

The 2gal Firewall is again for 2 cars and will be used on the engine side of the firewall and the trany tunnel from under the car (before the Spectrum is sprayed).

I got a great deal and a coupon just before Christmas so adding the Firewall and Heatwave products just for the hell of it. From Ant's email to you I'd say he's pretty much spot on the amounts except for the LL Pro. I haven't figured how 10 sheets would fit in a 67 just yet. As I said.. 6 sheets I think would be enough.

I had my order within a few days from the time it was placed. They forgot the spray gun and the foil tape when packing it up but a phone call fixed that. Ant said he'd have them out that day for me which he did.

Hope to have the car on the road end of May / beginning of June. Hopefully the stuff works as great as its touted to.

Edit.. A few photos. The roof photo gives a good view of how much area a sheet covers. Took 8 full sheets & 1 cut to fill in a few areas.

 

I used fatmat. I am not really expecting a new car feel or a luxury type of quiet. I want it to be loud, it is a muscle car afterall. I am hoping to reduce the rattles and heat somewhat, that's all. And I think that is what most of these sound insulators are supposed to do. If I want quiet, I have my honda pilot for that.
