Noise & Vibration Coatings

Spectrum & Spectrum Sludge automotive vibration coatings

Another way to kill automotive vibrations and structure borne noise is with our acoustical undercoating. We designed our Spectrum noise damper coatings for exterior floor pan applications, but when used inside the car, these vibration coatings provide a seamless barrier that is nearly 300% more effective than tar boards and asphalt sound deadener mats at reducing unwatned road noise, engine noise and exhaust noise.

Spectrum™

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.

Unlike many aftermarket vibration dampers, 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 will reduce 300% more road, engine and exhaust noise than traditional OEM dampers and tar boards, all at half the weight.

Spectrum Sludge™

Spectrum Sludge™ is the thickest noise and vibration paste on the market. One coat is all you need to achieve the minimum effective thickness of 1mm but a total thickness of up to 4mm can be applied in a single coat if desired. Simply add a single 6 oz. bottle of Sludge Activator (included) to a gallon of our regular Spectrum coating to change the viscosity from chocolate syrup to peanut butter.
