Erik upgraded his Hummer with some other sound deadening and blocking materials to tame down that big ole diesel engine, but was left unsatisfied with the amount of tire and road noise that he still heard. Here is his story: "I spent thousands of dollars sound deadening the interior and reduced the decibels from 87-81 decibels on a '92 Hummer. After reading a suggestion on Second Skin's website to start on the exterior and apply interior sound deadening last, I applied Second Skin Spectrum just to the front wheel wells to test it. It dropped the decibels from 81-79!!! I can't wait to get the rear wheel wells done!" Check out our Spectrum 2 Gallon Spray Kit which is perfect for all four wheel wells.
Erik's Hummer getting a little flurry action.
A few 1mm layers of Spectrum applied in 2-3 coats throughout the wheel well area will knock down that tire and road noise with ease.
Spectrum on the exterior firewall area of the wheel well are, cures black and looks so darn goo on the Hummer!!!
Inside and ready for that Spectrum treatment in the wheel wells.
