There was a post about a year ago about noise reduction using some type of tape that you can buy at Home Depot. Does any one remember what that was called? You took off door panels and stuck it to the door. Thanks for any info.
Scooby -It's a worth while project. I would take out the back seat and sound proof the back of the cab underneath the window first. I got the biggest noise reduction when I did that to my truck. I think that area acts like a big drum. I did the doors also, but didn't notice much difference at all.
