I've ordered some carpeting (from Automotive Interiors.com)in order to start getting the interior into shape in my 51 Champion. Has anyone used any of the sound dampening underlayments available? I've read articles about DynaMat, DynaPad, etc. and other look-alikes. Besides being expensive, do these work well?

I'd like to reduce road & engine noise, and dampen any body-induced vibrations. Remember, being a Business Coupe, I don't have any factory-provided barrier between the trunk and passenger compartment (no back seat).

I don't want to throw away my money, but if anyone can vouch for these products, I might consider the investment. Thanks.

I buy the type that is single or double face foil ground-up cloth fibres 1/2" thick from "Speedway Motors". I have done several cars, this will not break the bank, and it does work. Price is about $25 for a 4x6 sheet. Many cars need more insulation if the AC does not quite work well enough. I just did the doors on my Stude. truck to insulate for outside heat, cold, door echo, and to improve AC. I have done the whole truck. This insulation is about $1.00 per sq. ft. Don't forget the area above the headliner. Double face under the hood will kill engine noise. You can pay up to $15. per s.f. but why. At the Goodguys and NSRA shows there will be vendors with tons of it for sale----what does that tell you. This will make a car very quiet inside--fill every nook and cranny. Order at least 3 rolls.......Brad

Paul,

I face the same problem you do with my '58 wagon. I've driven it a bit when I first got it and the road noise from the rear area is attrocious! Maybe even worse with the LONG wagon rooftop![xx(]
I bought the felt-backed stuff like brad talks about and carefully cut and fitted it to the roof in alot better fashion than Stude would have done. The end result is that the roof STILL resonates when I tap it with a finger. The felt goes and I'll be investing the big bucks in some Dyna-Mat. Not just for the roof, but for the spare tire well, inside the tailgate and under the rear seat and such. I want to be able to hear the radio/CED player without making my hearing any worse than it already is.

brad, I'm not saying what you're using is wrong. If it works for you, then that's a good thing. Any more tho, I'm not cutting corners as far as comfort's concerned.

Have you looked into the spray-on insulations available. Dyna-Mat would be a good choice too if you have the bucks........Brad

I've bought several rolls of foil backed insulation from JCWhitney and used it in half a dozen cars, under carpet, above headliner, against firewall and behind seats; still holding up well after fifteen years, cheap and very quiet.

The best product for deadening is the product used for High end stereo systems , name brands are very exspensive, it comes in rolls, with addhesive back and foil face , sticks to most nearly clean surfaces, we use it on all restorations and cover most all the interiors, works great as insulation and takes all the tin sound away, a no name product can be found under the title e-dead.
