Dynamat Spray Sound Deadner

ron69912t · 09-05-2002, 11:50 AM

I want to deaden the tinny sound from my doors when they close. I can't see how I could get the inside door skin covered with their rubberized sheet stock much less glue it in place properly considering the lack of access space to the back of the skin. I don't want to have to remove the window lifts either.

Dynamat makes a spray can product to deaden the sound. Has anyone used it on their doors? How did you reach all the door skin surfaces with the spray can? Do they have an extension nozzle?

I recall Zebart having 3 ft. long spray nozzles they inserted in small drilled holes in the door frame.

Would undercoating spray work as well??

Thanks,

Ron,

I have some info at home on another manufacturer of spray on deadening material.

I'll post it later on when I get home.

Ron,

Here is the website link and a pic of some samples they sent me a while back.

I used Dynamat Extreme inside my door panels. It's very sticky on it's own, and easy to cut.

I also rolled it down hard with a plastic roller.

So far, so good; the doors are Mercedes quiet on close now.

Thanks for the info Craign. I'll give them a call.

bmwloco: Did you have to remove the window lifts to install the DE sheet? How hard was it to get access inside the door to lay out the sheet.

Thanks,
Ron

It was really simple. Pull off the door panel, peel off the vapor barrier (if it has one) and then roll up the window with the handle (just slide it on).

Be sure to put the Dynamat down in as large of a sheet as you can. Once in, use a good wooden roller to "marry" it to the door as best as you can.

So far, so good with mine.

I installed Dynamat sound deadner sheets on the inside of the door skins this last weekend. WOW what a difference in feel and sound. The doors feel like they are made of solod steel and the sound is just as solid. No more tin can sound. Turned out better than I expected.

Bought the sheets from PP and followed the instructions. I also have Dynamat sheets on the inside surface of doors too, under the door panels.

Ron,

Did you try any of the spray on sound deadners??

I need to replace my engine damper pad and am seriously consider trying one of them. I think combined with a pad you could reduce some serious noise and vibration.

Craig:
I thought about using the spray only but ended up with the sheets of Dynamat for the door skins. Although, I did spray the areas that the mat did not cover and the bottom of the door frames as best as I could with undercoating spray.

The doors sound and feel like bank vault doors!

I have to say my engine and related sound or vibrations are not overwhelming or too loud. I like to hear the engine go thru it's paces. I don't have an engine bay sound pad either.

The Dynamat mat and spray would be the best combination.
