Sound

[Jennings Fulvia]

Has anybody had any experience with using sound deadening material, such as Damplifier, in Fulvia. I need to replace the (what looks like hemp based) mat which is under the rubber boot mat in my series 3 coupe.

I've used Dynomat on the larger panels (roof, doors and around the rear arches) and some anti-booming material on the floors.

As the car hasn't run yet I can't give an opinion as to how well it works.

I have been using a paint stripping heat gun to melt off the bitumen sound proofing material on the floor and inner arches on my Fulvia project.

I was also planning on using Dynomat but only becuase that what they use on that TV show in the states called Overhaulin'

With all their resources I figured it must be the best if they use it.

Good job I melted it all off BTW, I found loads of surface rust hiding beneath it.

I guess the water crept underneath it and got trapped.

That's the only potential negative I've found. I haven't used it in the Lancia yet, but have it in my Alfa Giulia Spider. Adds a real feeling of solidity...less of the tinny quality. If the sheet metal seams are waterproof, I doubt there would be much problem with water getting behind the Dynomat. In an open car that is another matter, tho.

I'd recommend using Dynamat Extreme everywhere, not just overhead under the headliner.

Where did you get it from Ed ?

Just Google "Dynamat Extreme" and you'll get more hits than you can shake a stick at, it seems that the boys who like to turn their cars into mobile sound systems, use it a lot, going by the sites that cater for them.

As Brian says, a search will turn up too many sources, if anything. And I'd recommend using the "Extreme", which has the high temperature adhesive, even where it might not be strictly necessary.

I'm in the same situation as the thread starter, Jennings Fulvia, except I don't have the original hemp-like mat. Luckily the rubber mat is there. People have suggested Dynamat/extreme, but how exactly would you use this in the boot? I wound't want to stick it on the boot, partly because of the complex shapes, and I want to be able to inspect for rust. I've heard of using some fibe-based carpet underlay - thoughts? Does anyone know anything about the nature of Damplifier? Does it just lay in loose?

In the boot, I only use Dynamat Extreme under the rubber mat on the floor, and then only at the periphery, around the gas tank. It cuts out some road noise, but you'd never mistake the car for a Rolls. The problem with fibre matting is that it can hold moisture.

I've used this before, and my dad has it in his Aurelia. It works very well.

Find yourself a breaker who breaks mercedes or ?audi's or somesuch, ask if you can by undercarpet insulation, this is usually water resistantand from something like a Merc you will get a piece large enough to do the trunk/boot.
In my 2c I've used a cotton felt type material under the mats, as the mats are loose laid it's easy to check for damp.

PReviously I've also used something similar, and if you put it latex side down you should be safe if any wet gets in.

Well thanks for all of the advice and experience.
I have checked some other forums as well, and most are saying Dynamat Extreme is the best, though it is expensive, and of course it is heavy.
Part of the issue in the boot area is to smarten it up a bit, so I think I may resort to Dynamat first, then perhaps a felt layer on top of that, followed by the rubber mat, making sure of course that the petrol tank etc are all accessible.
