Re: Sound deadening ????

I'd be curious as to what others are using. I was planning on using Thermo Tec's heat and sound suppressor (https://www.thermotec.com/products/s...at-control-mat) this spring when it gets a bit warmer......

I used damplifier pro by second skin on my 68 Camaro. Very high quality product that is easy to apply. I put this on both door panels, trunk and lined the floor panels. Made a huge difference in reducing vibration and engine noise.

I used B-Quiet Ultimate then went over with their v-comp just on the front and rear floor. My car is LOUD and you can have a conversation in the car with the windows open normally. Also no heat at all from the exhaust tucked tightly to the floor or from the firewall. Super happy with the price and the results

I use a like product from Home Depot, a little thicker and better heat and sound proof compared to my Hushmat car with the same drivetrain. Cost is very attractive about 25% the cost of Dynamat. Foil backed and very sticky. Comes in 12" rolls in the insulation department.

Re: Sound deadening ????

I found that on the floor just go 80MM and whatever you get will likely be fine.

If you're using it on vertical surfaces, however, get the good stuff so the glue holds. Also clean the surface well before sticking it on.

I used both of the Lizard skin on the floor, firewall, and roof. I then put the Lowe's/ home depot stuff on the floor and the sides. It is still hard to have a conversation in My car with the Windows down around 45 mph. I have a 302 with a magnaflow 2.5 X pipe system out the rear. I have heard of the Lowe's/depot stuff falling down from the roof. I can't say why, it could be the product, or the prep/ install. Just my 2 cents.

Re: Sound deadening ????

I always used Dynamat, later Dynamat Extreme. It works as advertised. It sticks and will not fall off with time. I think you have to freeze it for it to be removed. It provides sound deadening and reduces the heat transfer into the cabin of the car.

There use to be some good information about the product on the internet years ago. I saved some technical pdf files that show just how much it reduces vibrations. If someone wants a copy, send me a note.

There is a aluminumized tape that should be put over the seams. Many people don't use the tape. Dynamat is like a radiant barrier in your attic of your house. The shiny aluminum on the mats and tape reflect the heat away from the inside of your car. Also the tape helps prevent water from collecting in the seams between the mats.

There are other manufacturers that make products similar to Dynamat. I am sure some of them work just like Dynamat. Some of them will smell bad for a few days. Dynamat does not stink, if that matters.

Dynamat makes a product that goes under the hood of your car. It is called Extreme Liner. It is made of neoprene foam, acoustic lead, acoustic foam, 3 mill urethane top outer covering. I stuck this under the hood of my trunk. After 16 years, it has yet to fall off. This made the most dramatic reduction of sound in my truck.

On my Firebird, I used a combination of Dynamat and Lizard Skin. I used the Lizard Skin for areas that are hidden from view and might get wet. It can be painted or sprayed on. It has the advantage of sealing the metal. I painted it in the inside of the cowl panel where the wiper transmission goes. I painted the inside of my quarter panels and doors before I installed them. I painted it on the under side of my trunk pan where the gas tank is located. I poured it in the inside of the deck lid.

Money can't buy you happiness but it can buy you car parts which is bout the same thang.

Re: Sound deadening ????

since they make sound deadener from butyl rubber, I went to my local roofing company and got their heaviest rubber
I am quite happy with it. I have straight 2.5" stainless pipes out the back and can have a conversation

I don't really have any across the board perspective on this but I am installing 80 mil Noico in my 69 as I type. It lays down well, is sticky as hell and common sense tells me once Dynamat's patent wore off the sky was the limit for competitors. Essentially some kind of elastomeric, tar-like substance bonded to a reflective metallic backing and voila!

This may be oversimplifying but considering all the varieties with the exception of the really specialized materials are essentially the same product not sure a huge price swing is warranted. I bought two boxes of the Noico material for about $125 on Amazon and it's enough to cover every square inch of the interior so we'll see.

Good luck with whatever you choose.

Re: Sound deadening ????

I used this roll of stuff that seems vary similar. It might not be quite a thick or sticky but it seems to do a fairly good job https://www.amazon.com/Thermwell-FV5...SIN=B000IO6Q2Y I got mine at Lowe's.
