Has anyone put sound deadening on there floors ? Did it make a difference ? What about the trunk floor ? Got a chance to buy some DYNO MAT brand at a good price. Wanted ta see if it is going to be worth it.

 

I used DYNO MAT on the floor of my (Please don't hate me) '67 Chevy P-Up and it made a huge difference. The road noise was cut down to almost nothing and the heat in the summer was a welcome side effect. I plan to use it in my '79 d100 when I get to that point. I would recommend it.

It must be applied properly, which is pretty easy, but the instructions need to be followed.

 

thanks ill give it a try ill let you know what I think

 

The only thing that I don't like about dynamat is that it's heavy and it's not nice to pull up if you need to. I've built three chevys for a dad a two sons very expensive cars that they put that product over every panel in the interior of the cars. Roof, floors, inside the doors and quarters, I'd hate to guess how much they spent and how much weight they put in the cars. But they ride nice and there quite.

I think the front foot wells and maybe the rear and possibly a half strip in the doors is all I would want to use. If insulating under the headliner there are lighter products available at the home depot's that would work for far less money.

 

Agree, I just used on the floor boards from under the gas tank to top of the firewall. Luckily I never had to remove it!

 

It is a pain if it's on the inside of body panels like doors and quarters that get damaged and need repair. You need to remove it to do heavier metal work, it melts and burns with heat and changes the way metal moves as your trying to straighten it so it's no fun.
