Product Description

Spectrum - 1 Gallon

*MADE IN THE USA*

Spectrum™ is a high heat, water based viscoelastic polymer damper. Formulated by Second Skin with mica, talc, calcium and crushed rubber to reduce resonance and thermal transfer. Apply to prepared sheet metal, carbon-fiber, fiberglass or aluminum. 

Stops vibrations in a similar manor to holding a wind chime or bell. Once the vibrations stop, the noise stops.

The next step is to reduce air borne noise by installing a noise barrier MLV (Mass Loaded Vinyl) Luxury Liner Pro on top of Spectrum

Each gallon of Spectrum will cover 10 sq ft at the recommended 3 coats for a total of 3 mm thickness. Each coat should be applied at 1mm thickness 30-60 minutes apart. Once the final coat has been installed, allow 24 hours before the next layer of product or upholstery is installed. Spectrum may be painted or covered with a bed liner after 30 days.  

A water based primer must be installed to plastic, aluminum or fiberglass prior to installing Spectrum.

Application surface should be dry and free from rust, oil, dirt and debris. Denatured alcohol works well to clean leaving no film. For high rust climates and previously rusted metal install POR 15 first. 

*Spectrum cleans up with water*

* 400 degrees heat rated*

* Minimum installation temperature 50 degrees F*

*DO NOT FREEZE* If product freezes do not mix, shake, or move until completely thawed. 

Spectrum and Spectrum Sludge are not bedliners and may be damaged by foot traffic.

Spectrum's shelf-life is six months stored at room temperature.

FAQ

What is the difference between Spectrum & Sludge?
Spectrum and Sludge are nearly identical products. The only difference is the viscosity. Spectrum has the consistency of heavy chocolate syrup and is easy to spray, brush or roll on. 

Sludge has the consistency of peanut butter and is too thick to spray, but can easily be applied with a putty knife, trowel or gloved hand. 

How long does Spectrum take to cure?

After 30 to 60 minutes Spectrum is dry to the touch. 7 to 10 days Spectrum reaches full vibration deadening properties. After 30 days Spectrum my be painted or a Bed-liner installed on top of it.

When can I put my upholstery back in place?

24 hours is recommended. 

What is better, Spectrum or Damplifier?
Both products are designed to do the same basic function. Reduce noise through the reduction of vibrations. Both have their place, and both excel at specific frequency ranges. This is why we suggest using a combination of damping mat and coatings.

Install Damplifier Pro on interior sheet metal then use Spectrum for the hard to reach locations. 

Install Damplifier Pro on interior sheet metal then apply Spectrum to the underside of the cars floor pan and wheel wells. This will create a sandwiching of the sheet metal between two CLD's

  1. Great Prouduct!!! 5 Star Review

    Posted by on 2nd Sep 2017

    Used a paint brush to apply it on my wheel wells, was easy no mess...With the addition of the Damplifier Pro in the interior this product works great and I haven't even purchased the Luxury Liner Pro yet... So far I'm very satisfied!!!

  2. Not what I was hoping for... 3 Star Review

    Posted by on 26th Nov 2016

    I am doing a van conversion and had two goals for this product: 1) provide sound deadening for the floor area, and 2) provide a rust barrier coating for any trapped water under the wood floor. I believe the second goal was attained, but sadly it made no difference in measured sound reduction. Still, I would say it was worth the effort. And it is an effort. I laid down 4 gallons in six coats over the course of a week. Perhaps I didn't lay it down thick enough for each coat, but I needed a cured surface as I had to walk on it to do the actual spraying.

    Cleanup is a task. Make sure you do a thorough job of cleaning the gun after each use. Also, I bought the recommended gun as part of a package. I think it was worth the extra cost rather than trying to source something separately.

    YMMV, but in my case the floor was apparently stiff enough that it made no difference in sound deadening.

    (Second Skin Reply: Each gallon of Spectrum will only cover 10 sqft at the recommended 3 coats applied in 1mm layers each coat, with 30-60 mins between coats, for a total thickness of 3mm. 4 gallons would only cover 40 sqft which is the average floor size of a 2 door car. The average van customer requires 10 gallons and above because vans are usually 100 sqft or more easily (most van customers use 15-20 gallons). We would recommend you calculate your total sqft and then use 1 gallon per every 10 sqft for proper coverage. For any questions regarding the application process or sqft amount needed for a project, do not hesitate to cal 1-800-679-8511 for some help with your order, Monday - Friday 9 am to 4 pm.)

  3. Much improved 5 Star Review

    Posted by on 28th Oct 2015

    I'm running an 82 diesel vanagon. I've installed CCF, MLV & some CLD tiles. They helped for sure. But--when I went back and put spectrum over the engine compartment I noticed an even better improvement. It took me six coats to brush on all the product. it goes on quick and is easy to work with. I thought I was playing mind games until my wife even agreed--it is much quieter. If you've got vibration and noise, consider Spectrum it has worked for me.

  4. Easy to use and Great Results 5 Star Review

    Posted by on 3rd Mar 2015

    I got this Spray On/Brush On Spectrum for my wheel wells, to quite down my bigger tires. I sprayed it on at 3 coats equaling about 3-4mm and achieved great results. I can not believe how much of the tire noise it absorbs. Definitely will suggest Spectrum to my friends and family. Keep up the great work Second Skin.

  5. works fine 5 Star Review

    Posted by on 1st Nov 2014

    this seems to be a real good product. went on good with brush or roller. thanks.

  6. Exactly What I Was Looking For! 5 Star Review

    Posted by on 11th Jun 2014

    The doors on my 1971 Camaro are super long and make a ton of noise. I wanted to add sound deadener, but Dynamat would add weight which is really hard on the door hinges on these cars.

    I decided to try Second Skin to see if it would help. I bought one gallon and the spray gun.

    I've never done any spraying before but it was super simple. Just pour it in the spray gun, set the pressure to 80psi and fire away. The only advice I have is to get a few disposable funnels which helps makes clean up a breeze. I also taped everything off carefully to avoid overspray, but I was impressed with the relative lack of splatter (given the type of material).

    The spray gun has a "tip" on the end which enables spraying through the access holes in the door. I had removed the windows, regulators and locks which made it easy to cover everything.

    With one gallon of Second Skin Spectrum, I was able to apply 4 coats on each door (about 2-3mm) and 2 coats under the dash on the back of the firewall.

    I could definitely hear the resonance difference when tapping my knuckles on the door (before and after). Thanks!

  7. great stuff, esay to apply 5 Star Review

    Posted by on 28th Oct 2013

    I insulated some of my Porsche Cayman with acoustic mat material, which did less than I was led to believe. So I did some research and found Spectrum Sludge. I covered the wheel wells and bottom of the rocker panels with it and was pleasantly surprised to find that doing just these areas had a much greater effect than the many square feet that I covered with the mat. It went on easily with a brush to the desired thickness, which I checked periodically during the process. Clean up was easy and the staff was very helpful as well. I highly recommend this product.

  8. great stuff 5 Star Review

    Posted by on 1st Jun 2013

    I got the gallon bucket and gun. did my doors and all of my trunk 4 coats. Sound from my exhaust was way quieter before I even put the overkill on it.
    spend the extra money and get the gun will make it easy to get it on nice and even. love that it is water based easy to clean up little spots of overspray on my window.

  9. Extremely easy to install, and very effective. 5 Star Review

    Posted by on 6th Nov 2012

    Extremely easy to install, and very effective. I used Second Skin Spectrum to quiet down the road noise in a classic '63 Merc, and it functioned perfectly. Very easy to brush and spray on, and dried quickly with no residual odor, Highly recommended.

  10. I’ve used 3 types of mats and Second Skin Damplifier wins hands down! 5 Star Review

    Posted by on 6th Nov 2012

    I’ve used 3 types of mats and Second Skin Damplifier wins hands down. I'd recommend this product to anyone. I also applied a gallon of Spectrum to my rear quarter panels and wheel wells. After driving to work today for 20 mins, I noticed the rear is much quieter. The smell after application does not linger like other liquid dampers, and unlike some products, the Spectrum dries a dark grey. Since it is water based, clean up was a breeze. Highly recommended!
