Correction - CLD - missed it by 1 L & 1 D .... thanks for the spell check or would that be an abbreviation check. 
As far as your comment about doing it right, all I can tell you is after installing coil overs which shifted the body load from the inverted leaf springs to the upper body shock mounts, the rear cabin resonance was almost unbearable. No way were you able to listen to music or even have a discussion with the person sitting right beside you. After the Second Skin / VetteNuts kit which had Ensolite applied which is a superior high frequency acoustical and thermal barrier which breaks up and diffuses unwanted noise incredibly well, the inside the cabin resonance is gone and driving / riding is very enjoyable.
Yeah, I do agree sound deadening is an art form but there's more ways to do things than only the route you took.......
But thanks for dig ole "master vette sound deadener dude"...

Okay for the record, it's not CDL, it's CLD. And it stands for "Constrained Layer Damper." Dynamat is one of the many examples of CLD's available on the market. It's nowhere near the best available, but it is the lightest (depending on how much you install), which makes it very popular. CLD's do NOTHING to dampen, absorb, or mask sound. They absorb the vibration from the panel it's applied to, in order to prevent frequency resonance from the panel. Put another way, it stops a panel from being noisy or acting like a giant tuning fork. If you really are after "quieting" a compartment, you MUST have a layer of MLV (mass loaded vinyl) as that alone "absorbs" sound. You also need a "decoupler" to separate the panels from each other to further isolate panel resonance. Sound deadening is an art form in these cars and takes a LOT of time, effort, and money to do it right. If you want to see this in action, check out my build thread where I begin the deadening process.
A combo of CLD, MLV, and CCF/HMF, is how to do it right.

What product would you recommend in place of CLD Tiles that's now out of business?

The best available was "SDS" (Sound Deadener Showdown) CLD tiles which got bought by a dude named Nick who now runs Apicella Auto Sound of New York. He bought the materials and patent from the original designer and maker of the SDS tiles. But he does charge a serious premium for them now. If you want the next best, the Kno Knoise Kolossus is the guy you want.
