Was talking to my buddy, for some reason he has a new Jetta. He's also into stereo competition. So today he says he wants to tear out the entire interior and Dyna-Mat the pass compartment & trunk. He found Dyna-Mat on eBay for $150 for 36 sq ft., says he'll need a bit over 1 'kit'.

As I would like to do the interior of the B-59 also, we discuss splitting a kit. I dont want/need to do my trunk, and I really have no 'pillar area' to cover, plus the roof is rather small (shorter than it is wide), but I wonder exactly how much area the B-59 has inside. While I'm obviously aware my car is somewhat wider than a Jetta, perhaps without the trunk I might be closer than I think. I go home & measure & calculate.

Adding a bit of overage to be safe: 94 frickin' sq ft.

Not looking to shell out $500 for this, so it's back to researching alternatives.
FatMat is a competitor, & it's cheaper, but not radically so.
Lizardskin, I'm not yet convinced of the results.

Anyone here use any sound deadener products?

I haven't used it personally, but a friend used Damplifier in the trunk of his Camaro to quiet the drown of his Corsa exhaust. Made a noticeable difference.

If you're interested, there's a whole tutorial on LHF for sound deadening your car.

I've read numerous car forums on the subject, but there's ALWAYS differing opinions.
I double-checked, and I can get 100 sq ft of FatMat on eBay for $150, which is a hell of a lot better than 450. I still haven't found a apples-apples comparison of the two, tho.
I'll check the LHF thread, DF.

I will say while it is pricey, Dyna-Mat is freakin amazing. My overbuilt (according to the wife) suburban has racing headers and straight 3 inch exhuast back to exhuas tips. It did have a loud Humm till I did the floor in DynaMat and boom all the noise was pretty much gone. My wife is mucho Happy.

I know it costs, but it is worth the price.

^ That may very well be. Question I have is; is there a competitor that delivers -say- 75% of the performance for less money?

Maybe I should do the firewall/floor/ rear bulkhead with D-M and the doors/roof with something else.
Problem remains- the B-59 is still so freaking huge. Aforementioned floor area is over 55 sq ft.

FatMat doesn't seem to be getting good reviews. Appears to not stick well and has a nasty odor, as it is closely related to roofing materials.

^ It's butyl rubber based, not asphalt (unless they have that line too).
I've also read numerous comments from those who've used 'Peel-n-Seal' asphalt-based product that it doesn't smell. Still, I would avoid putting it on the roof or doors in case excess heat made it move. I did pick some of that up but haven't installed it.

This would be totally simple if money were no object.

I would suggest you do the floor in DM and see how you like the sound, if you feel you need more insulation, then do the firewall and doors. Think of the insulationin phases. I have not found anything to equal even 75% of DM insulation properties and trust me, like you I wish money was no object as the Suburban was freakin huge to due the whole floor.

Good Luck Balthazar,

It doesn't seem like you can go wrong with either Dynamat or Damplifier. Both work well.

The thread on LHF is well worth the read. Some good info about different products he used, the budget, how and where he applied the products (with photos).
