Sound deadening material?

[pdub]

If I put that stuff inside my skull will it dampen the sound of the voices? Nothing else has worked, especially at 1:00 AM.

I wouldn't recommend it on a living subject because it's not dampener, it's deadener.

Bummer.......

If you're going full quiet than cover every square inch!

You mean like this? That gets it all the way to the bottom of the backseat and it's a pretty good muffler by itself I'll bet. I've got a few more sheets left to play around with the piece of wood and in the trunk. When I put that wood in there I was just looking for appearance - fill in the hole where the upper backseat used to be. Well, I left an inch gap at the bottom of the wood so I've been riding around hearing everything that goes on in the trunk.

Red pool noodle to fill in that 1" gap at the bottom

I've been videoing all this for Weeville Garage. That was my opening line, except I said to call this a learning experience would be an understatement. The Kilmat stuff is working great in the trunk to seal off and secure that piece of wood.

We used to actually make a "package tray" to replace the base cushion as well....usually padding the mounting positions with closed cell urethane foam available at HVAC suppliers....put black carpet over it and call it done.....it often provided a good place for transporting items / or luggage....

Well, there it is. An ugly but very effective fix for the mess I made with that piece of wood. It's now really solid, it'll never rumble and rattle again. I LIKE it. My only concern is, when I take Red to the Concurse Duhlegance car show, will they make me open the trunk as part of the judging?



And after 4 days of silver sticky rubber panels I nearly forgot (and Unit DID forget) why I even flew into doing all of that. The next step is another thing I've definitely never done before. Thanks to the YouTubers, I think I can do it...

Fat Mat. I have used it, it was cheaper than the dyna mat, but not by much. worked good. been in the vehicle 10 years or so.

The large mass of woven material which will eventually become the carpet has been moved into the general vicinity of the inside of the car. I think I heard it say, "Nyah nyah nyah, you thought I would just go right in there, didn't ya?" More days for sure.

If it doesn't want to cooperate(Wrinkles) Use a blow dryer to warm the carpet in small areas.... NOT A HEAT GUN as a heat gun will melt and scorch carpets!

Or put carpet in sunlight on driveway, once warm, into the car with a sound deadner roller and some muscle.

I have to say that doing the insides of the quarters did wonders on the Riviera for quieting down noise and that was even with having no backseat or divider in for a while. Definitely going to do the roof and the trunk when I get there. Have to try to keep the heat out too as I'm basically running an AC compressor from an early 90's Civic so it's capacity is kinda limited for the size of the glass house and I live in TX now.

I've found that when I get the carpet where I want it it's easy enough to push down on the carpet and make the studs poke through. Maybe I'll enlarge the hole in the carpet around the stud, maybe I won't.



For the places where a push pin goes through the carpet, I cut a piece of brake line long enough to go into the hole and stop and I'll push down on the carpet to make a hole for the push pin. Is this something I invented or it this something like what everybody's been doing for hundreds of years?

I use a beveled (not sharpened for my own protection) bolt. Screw it in, let it punch through or help it with a rubber mallet, then screw it out as you bolt the seat back down.

Edit: By beveled, I mean cone-shaped, but flattened on the end. Easy to do on a bench grinder.......the biggest advantage to this method is the bolts will keep the carpet in place as you replace them with the correct bolts, and they put the seat in the right place as well..
