Spectrum - 5 Gallon Pail
*MADE IN THE USA*
Spectrum™ is a water based acrylic viscoelastic polymer damper formulated by Second Skin with mica, talc, calcium and crushed rubber to reduce resonance and thermal transfer when applied to sheet metal, fiberglass, or aluminum.
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*
* 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.

Stopping vibrations on metal panels is much like stopping a noisy wind chime with your hand. Once the vibrations stop, the noise stops.
Spectrum Kills vibrations in a very similar way. It stops sheet metal from vibrating, thus, reducing structure borne noise.
The next step is to reduce air borne noise by installing a noise barrier on top of Spectrum like Luxury Liner Pro.
Spectrum contains Mica, Talc, Calcium Carbonate, and crushed rubber. All of these ingredients help stop thermal transfer.
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?
30 full days to fully cure but will be dry to the touch in 30-60 minutes depending on the ambient temperature and humidity.
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 Spectrum to the underside of the cars floor pan and wheel wells. This will sandwich the sheet metal between Damplifier Pro & Spectrum.
