Dynamat in doors

[Ed S.]

I have to remove the door panels on my 64 convertible to replace worn weather stripping and window felts, and make a few window & lock adjustments. While I have the door panels off is it advisable / worth the effort to install Dynamat to the back side of the door outer skin (fiberglass)?

I am not looking to improve thermal retention nor am I concerned about "judging" but I am wondering if there will be any benefit to sound deadening. Would appreciate comments from anyone that has applied a Dynamat like product to their doors regarding any noticeable differences / benefits one way or another.

Thanks

Ed - Last time I had my door panels off the 65 Coupe, I thought it was a good idea to add some Dynamat to the inside of the outer skin of the doors but once the door panel was off, I realized access wasn't the greatest. Obviously with the window down, no access but even with the regulator up, it wasn't great. I had visions of adding a large sheet of Dynamat but wound up using small strips in an effort to cut down on noise/vibration. I did clean the inner skin well with enamel reducer first and the Dynamat stuck to it quite well. I do have side exhaust by the way and had already used Dynamat on the inside surface of the roof when I had to replace the headliner. Even if it helps only a little bit, I still think it was worth it.

I did the doors in both my cars.....it's snug but doable and believe it added a measure of quietening outside noises.

I don't know much about the stuff but it sounds interesting. If you have the glass and all the tracks out, like after paint, could you slip a piece down where the glass would normally be?

Other question does it hold water if it gets wet?

I just did it on my 62 and in my opinion it was worth it! Just my old 2 cents

Re: Dynamat in doors

Thanks to all for the comments on your experience with Dynamat. Based on your advice I will be installing it in my doors. For Mike, according to the Dynamat website, this stuff is waterproof - the foam does not absorb water and the adhesive that holds it to the surface it is applied to is water proof - just don't cover up any drain holes! For the record, I am not endorsing this product - but for those interested... here is the Dynamat website: http://www.dynamat.com/

Re: Dynamat in doors

When I built my tube-frame Grand Sport replica, I lined the doors with Dynamat - that application was simpler than with a production body, as the Grand Sport didn't use window regulators - it used a simple pull-strap arrangement with seat belt strap and hardware. Made a considerable difference in the feel and sound of the doors, as Dynamat is designed primarily for panel damping.

Re: Dynamat in doors

I did the doors in a few C1 cars and my 65.
Stops lots of noise and if you tap on the outside of the door skin it sounds substantial not tinny.
I also did the roof on my 65 and it helps also.
Dynamat Extreme is the way to go.
Another plus it is also MADE IN THE U.S.A.
