Dynamat and how to use it
 

I'm at the point where I would like to put a sound deadener in my 46 coupe. Can I install it over the old Ford factory deadener or should I remove that first. i'm not sure if it will stick to the old stuff or not and at the price one pays I want to do it right the first time. Any help and past experiences will help me.

Remove the old sound deadener for the new soundener to be effective. Check out Ebay for more affordable SD like Rattletrap, superstick. It is cheaper than the more popular stuff.

Spoke with these guys at SEMA. They said the surface did not have to be clean, just peel and stick.

I've peeled & stuck a lot of stuff. I've never had good results without cleaning the surface. The old ford inner floor coatings left a lot to be desired. Unless it is still good and solid with no cracks or delamination, I'd remove it. The floors on the early 50s cars suffered from a lot of corrosion under the sprayed on tar based stuff. They didn't prime well under it and corrosion got started with the first water contamination on there. 20-years later you have a Flintstones car. Caveat emptor on what salesmen tell you. My Grandmother was from Missouri and I think the "Show Me" stuff wore off on me.

While I've heard good things about Dynamat it is very expensive. I went with a foil faced jute product sold by J. C. Whitney and put it in my 45 pickup and boy did it make a difference. I bought a 4' x 24' roll and two cans of spray adhesive and it was enough to do the whole cab including the doors of my truck. Cost was less than $80.00 delivered.

Lots of discussion on this over on the HAMB and other sites where guys are looking for much less expensive alternatives. For example, go to your local builder supply store and find some foil covered stick on flashing that has the same qualities.

Now that is some high dollar stuff!

Re: Dynamat and how to use it
 

That would be Peel 'n Seal, used for roof flashing. I used it on the floor of my truck. Sold at Lowes, Home Depot, etc. Can't compare to DynaMat but it's a fraction of the cost.

Bituathane(?) or Grace Ice and water shield sold at roofing supply houses.
36" rolls X more than enough to do the inside.
A little over a hundred bucks a roll.
