Sound Deadener

I used 3 boxes of the noico stuff. In my 67 dart.
I did the compartment floors, entire trunk, made a firewall behind the rear seat and did both sides. Did as much as I could of the firewall. Also did as much as I could on the inside of the fenders at the rear quarter windows.
I eventually plan to get one more box to do the roof.

So I would say a total of 4 boxes

I should also add that I sprayed down lizard skin sound deadener.
Reason for all this was to deaden more sound for our 7 month old baby to cruise with us during the summer.

There is a recipe for a cheaper alternative to lizardskin.
