Noise Control Materials and Fehr Cab Kits for your cab

I haven't used this yet but bookmarked it from another forum member
who used some of their products and was happy with the results.
I think he used the product called "The Insulator" and used it on the hood and firewall.

Good luck and post your results!

Jeff
