Product Description

Spectrum™ is a water based acrylic polymer under coating designed to reduce sheet metal resonance and structure borne noise. When installed at 3mm it will help to create luxury car silence.

This kit includes enough Spectrum to cover 20 sq ft at the recommended 3mm (2-3 coats.)

Kit includes:

Spectrum is made with Cryogenic-ally manipulated polymers, crushed rubber, calcium and other elements to create a highly effect sound deadener. Spectrum has virtually no odor while being applied, and no odor once fully cured. Mask or ventilation system are not required during installation. PlastiWrap makes for easy masking and clean up while the WireTape creates clean lines for a professional look. 

Spectrum may be applied as an interior/exterior coating on any sheet metal: Doors, trunks, firewall, engine bay firewall, ceiling and hood. It may also be used as an acoustical undercoating on the exterior fender wells or floor pan to provide mechanical protection from rust.

When applied to the interior and exterior floor pan, Spectrum will reduce 300% more road, engine and exhaust noise than traditional OEM dampers at half the weight. Once cured it will form a water resistant bond and protect metal from rusting. Spectrum will withstand 400 degrees F. Install at-least 2" from the heat source. 

One gallon of Spectrum covers 10 sqft for the recommended 3 coats of 3mm

Each coat should be applied at 1mm 30-60 minutes between coats. Upholstery may be installed after 24 hours of curing time. Spectrum may be painted or covered with a bed liner after 7 days of curing time.

*A water based primer must be used before applying to plastic, fiberglass or aluminum. 

*Application surface should be dry and free from rust, oil, dirt and debri. Denatured alcohol is recommended to clean surfaces.

*Do not freeze. If product freezes do not mix, shake, or move until completely thawed. Do not apply product in temperatures below 50 degrees Fahrenheit.

*Spectrum will hold up to daily driving rocks/mud in wheel wells and under carriages. 

*Spectrum and Spectrum Sludge are not bed-liners. Heavy loads may tear into the product.

Noise Reduction Uses...

Whether you are looking to quiet down your hot rod, or make your daily driver comfortable as a luxury car, Spectrum has proven to be the most popular & most efficient coating on the market.

Here is a quick lesson: 

Much of the reducible noise in any car is structure borne, meaning it comes from vibrations, like a wind chime. Unlike wind chimes however, our cars are not tuned to any specific musical frequency, so what we end up hearing is the road noise, engine rumble and exhaust drone.

Stopping the vibrations on your cars 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 the cars sheet metal from vibrating, thus, killing structure borne noise.

Once Spectrum has cured, the next appropriate step is to apply a noise barrier on top of the vibration damper. Noise barriers like our mass loaded vinyl barrier Luxury Liner Pro

Mobile Audio

If you have an aftermarket, sound system, then you know that a lot of the musical energy is spent, and even wasted by vibrating and flexing the your cars metal panels. Not only are these vibrations loud, and obnoxious, but they also limit the potential of your stereo systems output

Spectrum will help improve your audio system in several ways.

Since it is a vibration damper it will obviously reduce the panel vibration caused from your speakers allowing your music to sound clearer. It also strengthens the cars panels helping to "trap" the bass in your car.

With stronger, non flexing panels, the energy is no longer being wasted and stays inside the car, making your music louder, clearer and less obnoxious to those around you.

Another way Spectrum improves your audio system is by reducing ambient sound like road noise, engine noise & exhaust drone. When you can quiet down the rest of the car, the stereo has less sonic real estate to fight for, and the perceived volume increases.

Even if you are using one of our vibration mats, Damplifier or Damplifier Pro, you can still stand to gain from a gallon or 2 of Spectrum. Adding as little as 1 gallon to to the areas of the car you are unable to reach with your damping mats, can help in increase surface coverage by as much as 15%.

Thermal Insulation

 Spectrum will help reduce heat. Spectrum is made with Mica, Talc, Calcium Carbonate, and crushed rubber. All of these ingredients help stop thermal transfer.

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 paint brush. Due to the ultra viscous nature of Sludge, only one thick coat is needed, making it better for quick and easy installs.
Once cured the products will perform exactly the same, weigh the same and will look nearly identical.

How long does Spectrum take to cure?
 Water based products like Spectrum will take 30 full days to 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?
We suggest that you allow a minimum of 2 days for Spectrum to dry before reinstalling your upholstery. 


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.

We suggest using Damplifier Pro as your base foundation inside the car, on all the panels hidden by upholstery, then use Spectrum in the hard to reach spots. (A single gallon can increase surface coverage by as much as 15% in a moderate size car which can mean a large reduction in unwanted noise.

Then use the Spectrum independently as and undercoating on the underside of the cars floor pan. This will sandwich the sheet metal floor between Damplifier Pro & Spectrum, allowing for the ultimate approach in vibration deadening.

Specification

Weight per wet gallon = 12.5 lbs.
Weight per cured gallon = 7.2 lbs
Coverage: 1 gallon = 10 sq ft @ 3mm thick (2-3 coats)

Spectrum has a shelf-life of six months, provided it's stored at room temperature.

Suggested Thickness:

Minimum =  (2mm)
Recommended thickness (3mm)
Maximum = (5mm)

*Spectrum is water based and will not adhere permanently to plastic or fiberglass without first using a water based primer.

*Application surface should be dry and free from rust, oil, dirt and debris prior application. We suggest using denatured alcohol to clean the surfaces because it does not leave behind a film like degreasers do.

*Do not apply product in temperatures below 50 degrees Fahrenheit.

In this video we are applying Spectrum liquid sound deadener on the hood of the Avenger. Spectrum is so easy to use my teenager can use it, perfect for you DIY customers and projects. Spectrum has a heat rating of 400 degrees as long as it is 2" away from any heat source. It will stop the vibration and structure borne noise in the hood and will also help with heat transfer through the metal to prolong the look of the hood paint.
