Sound deadener for 65 Mustang

[Rye425]

For 1965 Mustang Fastback

Well I'm at the point where I'm ready for the interior since I got all my trim and interior panels back from paint. I was wondering what some of you suggest or have done in regards to sound deadening.

I was at first just going to go with the standard underlayment kit but I have seen a few resto's with stuff like Dynamat / B-Quiet / PeelnSeal. Does anyone have any experience with these? Is it worth it?

I'm very happy with the results from Second Skin products. It's a peel and stick type of sound deadener, like Dynomat.

Here's a great website that compares modern sound deadener options...

I'll second the SecondSkin audio idea.

I used SecondSkin's deAmplifier Pro on my car - put 2 layers of it from the firewall thru the backseat - and it is working well.

I just finished installing rammat from Ram Audio and the difference is very dramatic. The product is a 2 stage process where stage 1 is a foil faced peel & stick rubber butyl product. I put 1 layer from firewall back and inside the rear wheel wells and qtr panels. I doubled up in a few key areas like the larger sections of the floor boards and under the rear seat, just above my Flowmasters. Stage 2 is applying a closed cell foam using spray on adhesive. The rug goes on top of this. I previously used the asphalt underlayment with poor results. Not even worth the weight it adds to the car imo. I drove the car about 10 miles last night and as I had hoped, all the annoying squeaks and rattles are gone. Driving over bumps no longer results in rattle trap noises. Makes the ride so much more enjoyable.

There are a lot of qood quality sound deandeners out there to choose from. If you stay away from the brand names like dynamat you can get a pretty good deal. I used two layers of .50 mil that i found on ebay. i got two rolls of 100sq ft for around 100 bucks each. it was just enough to do two complete layers. like i said, it was a generic brand but it was very strong made of butyl rubber with the aluminum layer on top. i was really happy with the quality because as i used the roller to shape it into all of the contours around the floor pans, the aluminum held up without tearing. the adhesive was also very strong. After i put two layers down, i added a carpet pad which i cut to fit and spray glued in before putting in the new carpet. A lot of work, but definitely worth it in the end.
