A friend had a couple strips of peel and seal so I tried it on the inside back of my cab with poor results. I bit the bullet and ordered a box of Eastwood's Thermo Coustic sound deadener while wondering if I was wasting my money.

I love this stuff!

I need to buy another box of Thermo Coutic to do the back of the cab and under the seat. I covered the floor from the seat forward and up the firewall and the kickpanels. I even put some scrap pieces on the back side of the dash. On my first test run of the sound deadener today, I got rained on. Then it turned to hail. The hail was quieter than the rain used to be.
