I am a carpet warehouse manager and am wondering about using a rubber acoustic type pad for the roof and behind the tank part of the cab & floor of my 51 AD pickup.Also is it beneficial for sound and insulation purposes to add an aluminum backed pad atop the rubber or vice versa.Is it overkill to use both? headscratch Thanks Again!
