Product Description

 B-Stock Damplifier contains 16 Sheets (12" X 24") = 32 Sq Ft. 


B-Stock thicknesses are less consistent than their A-Stock counterparts it is made of the same quality materials. B-Stock contains factory errors such as uneven edges, wrinkles, and/or thickness variances of +/- 25%. These defects are primarily cosmetic and will not effect the over all performance.

Damplifier and Damplifier Pro B-Stock - CLD Sound Deadener & Vibration Damper

B-Stock Damplifier/Damplifier Pro are self adhesive, foil backed CLD vibration dampers. Simply cut, peel & stick on any sheet metal/fiberglass to reduce vibrations & structure borne noise.

Foil - Annealed black foil is thicker and stronger than most.
Ultra-thick 6.5 mil. Thicker foil means better sound deadening, vibration control and heat dissipation. 

Butyl Rubber Adhesive - Highest quality Made In The USA
Less fillers and more rubber for the best vibration damping and noise reduction available.

The quality of the the butyl rubber and thickness of the foil create the overall effectiveness of any C.L.D.

 Typical Places of Use:

  • Door Skins - Outer Skin & Inner Door Frame.
  • Floor - From the front firewall back to the rear deck seat wall.
  • Firewall - Cabin side or engine side. (450-degree heat rating). 
  • Van/Semi/SUV Panels – Any sheet metal.
  • Pillars - A, B, and C pillars. 
  • Trunk - Floor, walls, lid, and spare tire area.
  • Generator Boxes - RV, Van, or any place a generator is used, place the product around the generator enclosure to kill the vibration noise (Must be alleast 2" away from the heat sources)
  • Computer tower walls - Kills the vibration noise resonating through the metal.
  • Headphone Mods - Over the ear headphones install to the inside of the shell to increase quality.
  • Screen Doors - Apply throughout the door to stop the cymbal like noise.
  • Coin Counting Machines – Install on the sheet metal.
  • Hospital/Warehouse metal Carts – Install to the sheet metal.
  • HVAC Ducts/Units – Install to any metal that is noisy.

** Use caution when handling edges are very sharp**

** B-Stock sold as is no return or exchanges **

Noise Reduction Uses...

Whether you are looking to quiet down your street rod, or make your daily driver comfortable as a luxury car, Damplifier Pro is the strongest, most resilient vibration damper on the market.

The first acoustical problem in any sound deadening project is structure borne noise This is the harmonics and resonance that is emitted from the cars sheet metal panels, like a wind chime. Unlike wind chimes vehicles are not tuned to any specific musical frequency. 

Stopping the vibrations is much like stopping a noisy wind chime with your hand. Once the vibrations stop, so does the noise.

Traditional noise mats are mostly inefficient mass loaders; heavy & foul-smelling tar boards that work by adding weight. This technology is over 60 years old.

Damplifier Pro is not a tar board. 
It is a constraint layer damper that converts the vibration energy in to low level heat. This conversion of energy makes it 300% more efficient than traditional tar boards and asphalt mats while weighing half as much.

Simply cut, peel, and stick to any sheet metal.

Mobile Audio

Aftermarket, sound systems lose a lot of musical energy in vibrating and flexing metal panels. Not only are these vibrations loud, they also limit the potential of your stereo.

Damplifier Pro will help improve your audio system in several ways:

1.Reducing panel distortion and strengthen the area around the speakers. 

2.Increasing the volume of your music by keeping the acoustical energy in the car. 

3.Reducing unwanted ambient noise like road noise, engine noise & exhaust drone.

To fully reduce road, engine, and exhaust noise, install Luxury Liner Pro on top of Damplifier Pro.

 Thermal Insulation

1.     Ultra-thick foil layer acts as a radiant barrier, reflecting heat away.

2.     Foil dissipates heat by increasing the surface area. 

3.     High quality made in the USA butyl rubber reduces heat transfer. 

 The next level of thermal insulation is to install  Heatwave Pro ,Luxury Liner Pro or Mega block on top of Damplifier Pro. 


 What is the difference between Damplifier Pro and Damplifier? Damplifier Pro is 2 mm thick and Damplifier is 1 mm thick.

The foil is the same at 6.5 mils.The only difference between the two is the thickness of the adhesive. 

 What makes Second Skin Damplifier different from asphalt roofing products or sound deadeners that come on rolls?

 Products that come on rolls are roof tapes relabeled as CLD sound deadener. Quality sound deadening vibration mats are manufactured in sheets. Unlike roofing products, Damplifier and Damplifier Pro use 100% butyl rubber. They are nontoxic, virtually odorless and designed by automotive engineers. Damplifier cannot be rolled because of the thickness of the foil. Thicker foil means better vibration control.

How much CLD deadener do I need? Covering the center of the flat panels of sheet metal with as little as 25 percent will greatly reduce harmonic distortion. 50 to 100 percent may be necessary depending on the intensity of the audio system, road noise, engine noise and exhaust drone. Applying a MLV noise barrier like Luxury Liner Pro on top of your CLD sound deadener will more than triple the sound deadening results.

    The doors on my old Ford pickup sound like my parent's Cadillac!

  3. Only the Best 5 Star Review

    Posted by on 2nd Jun 2017

    This B-Stock is better than the "others" A-stock. If you want sticky, noise killing, non-smelling, quiet down deadner; slam some on your car, truck, hell even your girlfriend if she's too noisy. There's no better product to kill the noise, whatever that may be, than Secondskin!

  4. First time user 5 Star Review

    Great product I will most definitely be ordering more in the near future.

  5. B-Stock worked For me 5 Star Review

    Posted by on 4th Apr 2017

    I was directed by a friend to try the B-Stock to keep down the costs of treating the doors on my truck, never using this type of product before I was happy with how easy it was to work with. I will be purchasing more to complete the soundproofing project.

  6. Great stuff 5 Star Review

    Works very well easy to install

  7. Solid product 5 Star Review

    Posted by on 12th Aug 2016

    Easy to work with, forms well to uneven areas, rolls out smooth, looks great and from what I can tell so far adheres strongly. Wear gloves for sharp edges when cutting. As far as B-stock goes it was in better condition than expected, no missing adhesive or horribly blemished areas.

  8. AMAZING! 5 Star Review

    Posted by on 4th Jan 2016

    Great Stuff. I was skeptical. It really toned down all the vibrations around the car, horizontal and vertical surfaces.

  9. This product works great! 5 Star Review

    Excellent quality unmatched by any other product.

  10. This stuff works! 4 Star Review

    Used this on a triumph when redoing the interior, makes a huge difference, the car is much quieter and feels more solid,
