| Here's some photos of my sound deadening project. By the time I get done this truck will sound like a Lexus inside. I started by basically ripping the whole interior out. Then I did a layer of Rockford Fosgate spray on sound deadener on all surfaces as well as the many cavities in the doors and cab. This has to dry for about 24 hours to fully cure. I then purchased a roll of a roofing ice and water shield called Bituthane. It's about $100 a roll and is available 3/16" thick and has an adhesive backing. This is similar in construction to the more expensive Dynamat type products, but goes a long way. Simply cut into small enough pieces to work with. About a 3' x 3' piece is the most you want to work with. Stick it where you want it, a small roller is advised to help smooth it on. A heat gun is necessary as the adhesive is heat activated. I did five layers on every surface. As you can see, the whole truck is steel. Wind going over the sheet metal creates vibrations, which = noise. The object of sound deadening is not to absorb, but to dampen these vibrations and eliminate unwanted road noise. Now, if they'd only make something for glass! |
