Product Description

Spectrum - 5 Gallon Pail

*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 on metal panels, 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 hour drying time 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 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. Its almost cheating 5 Star Review

    Posted by on 1st Sep 2017

    I'm using Spectrum as a sound deadener and under coat for my Ultima Evolution and it works great! It's very easy to apply, and cleans up unbelievably well. I've used it on steel, Aluminum and fiberglass, putting an etching primer down then the Spectrum. It's also California friendly for all you west coast builders out there.

  2. Excellent Sound Management 5 Star Review

    Posted by on 29th Oct 2016

    Spectrum takes the tingy sound from metal or fiberglass and makes it sound like it is 3 feet thick.
    All vibrations are absorbed and also creates a protective barrier from road debris.

  3. great product 5 Star Review

    Posted by on 27th Jul 2014

    Have only done the doors on my suburban so far but what a difference. Radio sounds better and the ride is much quieter. I can't wait to do the floor pan and wheel wells. Am going to do the wife's Camry next.

  5. Thanks again for all your help 5 Star Review

    Posted by on 6th Nov 2012

    Hi Anthony, We ordered 6 gallons of Spectrum & 4 sheets of the Overkill from you last week. I just wanted to let you know how much we appreciate your customer service. You should be very proud, my father mentioned to me that he was extremely impressed with you & your company. I know that’s not saying much since you have never meet him before. But being his son I know how important customer relations is to him. He's spent almost his entire life in a "Sales Related Field" real estate to be exact so he can appreciate someone who takes their time to be as courteous & helpful as you. Thanks again for all your help & expertise, the product arrived on Monday and I am going to be applying it tomorrow afternoon.

  6. dubbed the name "GO TO GUY" 5 Star Review

    Posted by on 6th Nov 2012

    I was referred to Anthony by Steve at Digital Designs in order to fully deaden my 05 Chevy Avalanche being used as a demo vehicle. Anthony was dubbed the name "GO TO GUY" to kill unwanted vibrations. I called Ant and told him my audio specs and he gave me a sponsorship along with the deal of the century. I received 3 Shop Packs of Black foil Damplifier Pro, 3 Gallons of Spectrum, Spectrum spray gun, Fury knife, and wooden roller. All I can say Ant is WOW this stuff does everything described and more. I put 2 layers of Damp Pro on the entire inside of truck and 4 coatings of spectrum on the inside as well as under the truck. 99 is because i took the midgate out and i hear bed noise. Thanks again Ant and i`ll be contacting you shortly about getting 10 sheets of Luxury Liner Pro.
