Sound deadening in doors?

I'm installing Dynamat sound deadening material to the interior of my 67 vert. Is anyone applying it to the inside of the door skins? And if so how much? My concern is the additional weight and/or the long term effect it may have on the door skin after years of opening and closing. I could go with Lizard Skin in the doors, just wanted to gauge what most are doing/did.

I added to 4' x 24' strips of Dynamat to the inside of the door skins (one above the body crease and one below it)Ö
Now my doors close with a 'thud'.

Re: Sound deadening in doors?

I put Dynamat in the doors of my truck. I stuck some on the outside skin and also to the inner frame. The doors were quiet. It never peeled off after 12 years.

On my car doors, I used Lizard Skin. I used a paint brush to apply the product. I painted the interior of the door.

I think Dynamat will make the door quieter and heavier compared to one that has Lizard Skin.

The inside of the door will get wet when it rains. Dynamat could hold water in the right circumstances. Lizard Skin will help seal the door from rain. If you use Lizard Skin, paint the seams where water could collect and don't plug the drain holes.

I use epoxy followed by Dynamat. Almost a full sheet. Itís all about mass and Dyanamat has a lot of mass...

Re: Sound deadening in doors?

Hey Mr Smith,

I see your doors were on a horses when you applied the LS. My doors are on the car. Will I be able to apply the LS product to the skin without it all running down into the bottom of the doors? This car will be garage kept and only see rain on special occasions. Would you say coating the bottoms of the doors with LS and two strips on the outer door skin like Thor mentioned would be the way to go? I respect your opinion because I've seen some of your projects and posts.

Re: Sound deadening in doors?

I think that I just realized that maybe I am obsessed with rust.

My original door had holes in the bottom were a seam collected water. The water entered through the window fuzzie, drained down the outer door skin and collected in the door seam. The drain holes are below the seam and only allowed the water to exit when the seam overflowed.

Lizard Skin is thick. It is thicker than the latex paint that you brush on the outside of your house. It is not as thick as toothpaste. It is not going to run if you apply it to a vertical surface.

Along with the rust, my door had some sound deadening material on the walls. I don't know if the factory or someone else applied it.

Sometimes simple projects turn into major projects. You might see rust inside the door when you pull the door panels off. The window mechanism is going to be in the way. Tape the window roller guides so that none of the Lizard Skin gets into the mechanism.

You can use a combination of Lizard Skin and Dynamat. I used Lizard Skin on parts that might be exposed to water and Dynamat on the rest on my car.

Mr. Don is right. Heavier mass will not resonate like a thin piece of sheet metal. They actually sell mats that have a lead lining. I am not about to cover my car in lead.

Mr. Fred's method is good. Using strips will be almost as effective as covering the door as one solid piece. Dynamat is expensive. If you use strips, make the surfaces that are not covered irregular in shape. Don't make it pretty. Non-symmetrical metal does not resonate very good.

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

Re: Sound deadening in doors?

I built my wife a car several years ago & for sound deadning it I used the bubble wrap insulation from Home Depot. I installed it with spray contact cement, & it work very well on cutting down noise & it does not weigh very much.
