Interior: Dynamat cover?
Guys, I need some advice. I'm overhauling the interior on my 71 C10 "shop truck". This is by no way a high dollar build, but I have done some nice touches and I believe the right way. My question is, after you use Dynamat(or whatever brand shiny silver insulation) and you have covered up the firewall, floorboard, and up behind the seat; then what do you cover the said Dynamat with that is not covered by the replacement carpet? That was the world's longest run on sentence... I don't really want to see shiny silver aluminum foil behind my seat(tank has been relocated) nor do I want to see it above the carpet line under the dash.
Any ideas? Carpet? Spray paint?haha. Examples with pictures would be great! Thanks! ![]()

Re: Interior: Dynamat cover?
I put replacement firewall padding on the front and will put carpet on the back wall. Eventually I will have a sound system (amps and subs) behind the seat.

Re: Interior: Dynamat cover?
Finish the deadening job with closed cell foam and mass-loaded vinyl?
Probably not what you wanted to hear.... ![]() I'd just get some more carpet or build a nice subwoofer cabinet behind the seats.

Re: Interior: Dynamat cover?
I laid down a Dynamat material, followed by Mass Load Vinyl, followed by aluminized closed cell foam. You can see it on my build thread below.

You did it right on the vehicle (it looks great btw!), but you got the order mixed up here. It should be vibration damper on the surface, closed cell foam, and the MLV last. The purpose of the closed cell foam is to isolate the MLV from the vehicle. I just don't want the OP to get confused.

http://www.soundproofing.org/infopages/flooring.htm here's a link to MLV which is used in the walls of home theaters etc. The stuff is great but it's very heavy and is hard to shape. I've also had issues finding a suitable adhesive to apply it to vertical surfaces such as the back of the cab and the inside of the doors. The best so far that I've used was Locktite 300. ![]()

Re: Interior: Dynamat cover?
Yeah, notchbackgta has it right. CCF's purpose is to isolate. So the MLV should be isolated from the surface of the vehicle.
Z10, I guess I misread your build page, b/c I thought you posted that you applied the deadener, CCF and MLV. Anyway, with your CCF having an aluminized layer, it should probably be decoupled from the vehicle, too. But, we may be nitpicking. I'm not sure how much you'd notice with a layer of carpet padding and carpet on top of all of that. It definitely is quieter than it was from the factory! ![]() BTW, if you go to https://www.sounddeadenershowdown.com/, Don, the owner, did lots of testing (a lot of his results were posted on an audio site I frequent.) He sells his own product now, but his site is still a good resource even if you don't buy from him. My .02 And sorry, mdeal, your original post has taken a bit of a detour. ![]()

I have the same situation. I bought several yards of that speaker cabinet felt/carpet to cover the rest of mine, probably going to use 3M super 72 blue spray adhesive to attach it to the surface of my sound deadening material...
you can find the speaker carpet/felt, etc.. Walmart. Ben ![]()
