My neighbor, also the owner of an '05 Mustang (V6) has mentioned a product which is sprayed into the door panels and other areas to help reduce road noise and give the door less of a 'tinny' sound when closing.
Has anyone heard of such a thing, or any other way of adding some soundproofing to the vehicle?
