Spectrum is a water based under coating designed to reduce sheet metal resonance and structure borne noise. It is a true visceolastic sound deadener that can make any vehicle quiet as a luxury car.
Now made with Cryogenically manipulated polymers and high temperature wax, Spectrum is the only product on the market of its kind! Spectrum can be applied as an interior coating on the sheet metal behind the upholstery, or as an acoustical undercoating on the outside of the floor pan to create tomb like silence and provide mechanical protection from rust.
When applied to the interior and exterior floor pan, Spectrum can reduce 300% more road, engine and exhaust noise than traditional OEM dampers and tar boards, all at half the weight.
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 virations 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
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%.
Anything you place in front of the heat source will help reduce or slow down the heat. Spectrum will help reduce heat to a small degree but is not specifically designed to do so. Any heat reduction noticed from Spectrum is purely a side benefit, not an intended result.
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? like allL water based products 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.
Weight per wet gallon = 12.5 lbs. Weight per cured gallon = 10.2 lbs Coverage: 1 gallon = 40 sq ft @ 40 mils thick (40/1000") or 1mm
Minimum = 40 mils (1mm) Reccomended thickness = 80 mils (2mm) Maximum = 120 mils (3mm)
*Spectrum is water based and will not adhere permanently to plastic or fiberglass without first using a self etching primer.
*Application surface should be dry and free from rust, oil, dirt and debris prior application.
*Do not freeze and thaw more than twice. Do not mix until completely thawed.

After installing a trunk pack of Soundqubed Q-Mat (which is awesome stuff too) I decided to try out 1 gallon of Spectrum, which I sprayed over the deadener I had already laid down. It worked great getting into those tiny spaces on the inside of the trunk lid where mat was not an option. It made a huge difference when applied to the rear wheel wells, with no interior installed, it killed almost all the road noise in the rear of the car. 1 gallon covered my entire trunk & trunk lid with 2 thick coats, and I still have a bit left over. The spray gun made it very easy to apply, but it can be brushed on too. There was NO smell at all, I couldn't believe it! Clean up was simple, just use water! I can't wait to get some more Spectrum and spray the inside of my door skins & front wheel wells. Great product here!
