Vehicle structural noise like road noise and tire noise start at the wheel wells—so if you want a quieter ride, this is where you start. Whether you're spraying the wheel wells from the outside or treating the interior arches, the right sound deadening product will knock down that noise before it ever reaches the cabin. These are the go-to materials built to take a beating from the road while delivering real results inside your vehicle. Quiet down the harshest part of your ride and enjoy the drive again.
Yes, sound deadening a vehicle's wheel wells is the best "bang for your buck" sound reducing treatment for road and tire noise. It only takes 2 gallons of Spectrum to do all four wheel wells, and you don't need to access any metal inside the vehicle. Typical results with a Spectrum treatment are 3-5 db quieter inside the cabin (20-30% reduction).
Do I need to remove the fender liner to apply sound deadening?
Yes, remove the liner! Sound deadening will perform best when applied directly to the metal. The liner is typically plastic and held in place with screws or clips, so it's easy to remove and put back. After applying Spectrum to a wheel well, give it 24 hours to dry before re-installing your wheel well liner.
