Just saw your pix, Skydive. Do you really hear a difference in road noise? I've never used any type of sound dampener in a car before, but I always thought that every single surface would need to be covered to actually have any effect. Of course those dampening products can get pretty expensive too, which is why I never bought any. With the amount of coverage you have on your doors and floor, if you say that you can tell a difference then I will probably do this myself also. Let me know. Thanks.
