For awhile I've been considering adding some soundproofing to my Focus. I've read a lot online about people using roofing membrane material as sound deadening, as it is similar to a lot of 'professional' sound deadening products. What I really want to know is: how much do I really need to apply?
I've heard that even a 1' x 1' square applied to a panel can make a HUGE difference in absorbing vibration and some sound. Is this true? If so, I can easily apply a little sound deadening to each panel on the car (doors, trunk, etc).
