Sound Deadener

It’s pretty idiot level to install. Put some bolts or something you can find by feel in seat belt bolt holes and other things you want to find afterward. It’s a real pain if you are a dummy like me & have to get under the car with a ice pick to find them later. The stuff mushes together, so you can use leftover pieces easily.
 
Idiot level. LOL Right up my alley. Well, it wasn't hard but it was HOT. Was 97 here today. That probably actually helped.

Yeah, the hot weather makes that stuff stick like paint. Take your door panels off and put some directly behind them. That helps a lot.

Some people cut up some squares of it and put some pieces on the inside of the outer door skin to damp vibrations.
 
That did turn out great, looks like the fat mat stuff I used and works great even inside down, have my hood and trunk lid lined with the stuff and the while trunk.

Did you put anything over it in the trunk to make it look nicer? Kitty wants me to carpet the trunk too. I guess I might.
 
Any reports of these products trapping condensation? Ill still use them as I will have A/C and want a fairly quiet ride, but wonder.

Yes I still put the rubber mat down in the back. Left it the insulation on the trunk lid, not sure if I'm going to cover it.

I don't think there's any chance of that after using the product.
 
I'll agree with that. lol
I read in this thread that you planned to install Killmat on your roof panel. One thing I would like to know is, in the heat in summer, does it stay in place? I have a box of the Kilmat and, left over from another project I have some Siless that looks almost the same. Cleaning the ceiling of the yellow glue from the factory roof padding is turning into a big job, especially at 77 years old. I'm scraping first with razor blade scraper and following up with lacquer thinner and/or weatherstrip cement remover. Results seem similar. But, it it'll take a lot of either solvent to completely remove the glue. Any idea whether or not the old glue needs to be completely removed? On other projects I've learned that these Kilmat sticks really well. My car is a '63 Dart wagon. Those grooves in the roof panel add interest while removing the old mat and glue. Anyhow, I'm close to just scraping and hitting it with solvent a couple times and going for it. Any cautions or comment?
Thanks

How have the results been? Really quiet? I imagine with all the bare resonant metal in these cars, the results would border on dramatic.
Man, the rattle is part of the Fun! But even me, 30 years ago, put new carpet in the 68 Coronet, after doing headers. Just to darn hot down here..

It ain't come down yet. The way this stuff works, the heat makes it all the more sticky. Kitty and I put it on when we had like three of the hottest days of the summer. It was over 100 all three days and that stuff stuck like the dung who flung. That's when it's easiest to work with is when it's hot. In fact, it says in the deestruckshuns to lay it out in the sun ahead of time and we did. Soon as it hit the surface it was STUCK. As of this summer, it's been on three years.

Thank you sir. I now have confidence that it'll stick and stay. By the way, the picture of your floor Fixmat installation went well and was well done.

Thank you. We worked hard on it. It's not really hard to do, but it was HOT when we did it (which I recommend) and we're a couple of old broken downs, so there's that. lol
 
But I'll add this.....if you do this when it's hot outside, make sure of your placement, because wherever you put it, it's stickin. lol

Yep, I'm prepared for sticking quickly. I've done floors and it does stick well. Thecleaning of the ceiling is coming along.
I sure like the early A bodies. Over the decades I've had 2 '63 Darts, 3 '66 Darts and one '72 Dart that I bought new.

I would sure paint the inside of the roof and let it dry good. The smoother the better. I didn't want to, but I'm glad I did it. It stuck good. When Kitty found out I was covering up all that bright red paint with Kilmat, she said NOOOOOOO. LOL
 
I tried to pull some off some months after I installed it. It was like trying to get gum out of carpet. I gave up. It is definitely forever once it gets hot.
