Technology Overview
QuietCar is an advanced viscoelastic polymer soundproof coating for all outdoor applications, specifically cars, vans, trucks and other vehicles. QuietCar can be applied by brush, roller, or sprayed on with the optional spray-gun for air compressors or an airless paint sprayer. The advanced viscoelastic properties allow the coating actually absorb unwanted noise and vibration, rather than just block it (which is what mats do).
Unlike mats, QuietCar can be easily applied to the exterior underside of the vehicle.
By absorbing vehicle body vibration, engine and road noise can be reduced by up to 20dB, depending on vehicle and application. This can make, for instance, subwoofers sound 3dB louder (the same as doubling the power!).
The more you apply (underside, inside under carpets, wheel wells, engine compartment walls, trunk etc.), and the thicker you apply, the more noise will be absorbed. One Gallon will cover about 40 square feet for good noise reduction, and about 20 square feet for best noise reduction. A typical car will use 2-5 gallons to quiet entirely, sometimes more if there are more surfaces to cover. However, you may coat specific areas of concern, such as the trunk or door panels, or floors with 1 to 2 gallons total. See the Application Note for more details.
In numerous studies, QuietCar out performed mats 2 to 1 in reducing noise and vibration.
