Sound Deadener

[joeko23]

Hey guys do you put any sound deadening material or spray inside the doors of 69 Camaro? I was thinking to spray boom mat spray in there since putting an actual material will be hard to get in there fully unlike a spray.

I was also thinking to use the boom mat spray in other crevices like behind the quarter glass, trunk, firewall, etc where it would be hard or impossible to cover with material.

Any recommendation also on which sound and heat deadening material to use on the floor, roof, etc where I can put material (not spray). I was thinking to use Hushmat, anyone have any experience with that? They have a complete kit for the whole car with panels already precut and obviously instructions on where to put what.
