I'm at the point in my project (a 78 ford crew cab so theres alot of surface area to resonate off of) that i will be driving it soon and i had a guy in my autobody class where he put down rhino liner first and then was going to put down dynomat. But he hadn't quite got all the way done and wasn't driving it full time yet. My question is has anybody tried this is it worth to do both. I was already planning on rhino lining the bottom of the cab and doing dynomat inside the cab. I'm tired of the road noise in the pickup that its in now and i really would like to get it to the point where its a comfortable ride. Any ideas would be greatly appreciated thanks.
