Tommohawk,

As a deadener, the urethane bedliner woould muffle the mechanical and resonances noises of the car it wwas applied to, not the sounds that are comming from other traffic.

Walmart(at least here in Savannah) sells a quart container of bedliner for $20.

OK, I'll see if the Walmart has any. You know I always warn against too much sound-deadening...
