Projects Dynamat alternative

Gettin ready to put some sound deadening material in the ‘29 and the only one I’ve heard about is Dynamat. Pricey but willing to spend the coin unless there is a product out there that works just as well at a lesser cost. I was also thinking of glueing jute padding on top of it for an extra layer of sound barrier.

I have used the Peel & Seal, seems to work good.

 

Big-box store.

 

Kilmat 50 mil 50 sqft Car Sound Deadening Mat, Butyl Automotive Sound Deadener, Audio Noise Insulation and dampening https://www.amazon.com/dp/B0751G6TMV/ref=cm_sw_r_cp_api_glt_fabc_2KFA7Q9N0THMZ5CR4WK1
This is what we used in our shit box.

^^^^^^^^^like he said. The Killmat works great and costs way less.

 

I don’t know about the jute padding though,they say it wicks up moisture and holds it.

 

I used Killmat in my 49 also.

 

IMO... use the jute, but don't glue it down, it holds moisture...

 

And Jute stinks when damp for a few days.

The OP should try Acoustic foam, or closed cell foam (used for holding heat in swimming pools)

 

I used killmat in the 57 Chevy, good price easy to work with.

 

I’m nixing the jute padding idea. Checked out the killmat n also found Noico on Amazon. Both look like they’ll do the job

I used the Kilmat in my 51 Merc. I would definitely recommend it.

 

Used Kilmat here with Noico insulation over it

 

Go to a Lowe’s and get the sealing tape for around windows, I believe it’s about 10” wide. I used it in my deuce sedan but it’s been a number of years ago.

 

EDIT:
I was living in Missouri at the time I had installed the window seal tape. The truck was black and it always sat outside.

A few years ago I used this on an OT truck door. It worked but after a couple years it started to melt and it ran down the inside of the door and out the weep holes and down the side of the rocker panels.

 

I've used it as well in a couple of cars, with very good results.

Beware of the Eastwood stuff, someone here posted a thread where the asphalt ran out and made a mess when it got hot.

 

I spent quite a bit of time last year asking myself which sound deadened to use in my Model A. Finally decided that every thing else is compared to Dynamat (which yes is more expensive than others), so I just bit the bullet and went with Dynamat. I used the Extreme everywhere I could attach it, the Dynapad in the roof and inside of the firewall, and finally added Dynadeck over the floor.

Super nice.

Haven’t had a problem with mine and the car has been on the road for five years.

 

Another vote for Kilmat
Used it in my 30 and my buddies 32

Whatever you buy, just make sure it's butyl rubber based.
The cheap asphalt based stuff, like the aforementioned Eastwood product, can melt at higher temps.
When it does, it's a complete mess, and can ruin your interior.

After reading as many posts as I could here about this topic, I went with Peel and Seal from Lowe’s. Prepped everything really well and it went on and stayed where I put it.

Never any odor, even from the firewall area which gets a bit toasty during warm summer days. The hotrod bumps and bangs are still there, just not as sharp sounding.

I’m satisfied with the product, and with the money I saved over the cost of the more expensive, “made for” products out there.

It did cut down on the amount of heat radiating through the firewall too.

 

I used Noico in my ‘30 Victoria. Did everything I could get to and as I remember it took less than 2boxes. Each box was 36 square feet and cost about $68 a box. I used the black color as I figured I wouldn’t complete the interior for a while and didn’t want to look at all that silver. Reasonably priced. REALLY deadened the sound. Very happy with it so far.

 

I used the stuff which is fitted under corrugated steel roof sheeting, about 1/4" thick, with reflective stuff on each side. It's called Kingspan here, probably something similar available in the U.S. The best bit was that it was free offcuts from a commercial roofing job.

 

Noico black on 3 vehicles now. Cuts down on heat transfer and does a great job at sound deadening. Doesn't have their name plastered all over it. Gene

 

There are many different products for sound and heat suppression. I used Dynamat and am very pleased with it. I used it because it was stocked in town and with shipping other products would have cost almost as much.
Bottom line is these products really work well. The difference in my car was crazy.

 

Lobucrod is a member here, he sells insulation for hot rods and gives alliance members a discount!

I suspect these anomalies could be related to Climate and storage of the vehicle...ie outside versus inside...he's in Finland which I don't necessarily associate with hot high temps but as we know in enclosed vehicles when all the windows are up on a sunny summer day temps over 100f are not unusual...assumption on my part but these are my first impressions...

 

kilmat in my daily, works great.

Lobucrod - bought some for my project - havent driven the car yet. Site seems dead, I cant find a source for it now.

 

I used Rattletrap by Fatmat in my roadster. No problems. If I remember they had free shipping.
Cheaper than Dynamat.

Me too. $16 for a 25’ roll, 5 rolls did the flirt and riff of my ‘52 DeSoto wagon. Great stuff.
