Unlike mats such as Dynamat and others,QuietCar coating is for all outdoor applications, specifically cars, vans, trucks and other vehicles. This coating can be applied by brush, roller, or sprayed on with a special spray-gun for air compressors or an airless paint sprayer. The coating actually absorb noise and vibration, rather than just block it (which is what mats do). 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)
