Well, in for penny...

I have about 18 sq ft of the Siless butyl/foil material left which is about what I need for the roof. Any extra will be strategically placed as a second layer.

I just ordered 20 sq ft of Noico Red 315 mil foam to go on top of the butyl layer.

I’m all in now, but first I need to figure out how to remove the headliner without staining or wrinkling it.

I’ll report back how it goes.

Wish me luck.

Good luck! Looking forward to learning about your process as well. It might be the first time a forum member has posted about headliner removal. This would also be useful information for those with dual camera dash cams.

There was another forum member who did it to install OEM roof rails on his LT. Unfortunately, he got caught up in the moment and did not take any pictures.

I'll try to take as many pictures as I can.

Well, I did it. It’s not pretty, but it’s done. Other than some slight wrinkling of the headliner which I hope will disappear with time, I also broke the round disk part of the passenger side sub visor mount. It all went back together so I may not even bother replacing it later.

The one major thing that I had not considered is that various wiring bundles are glued to the headliner. I even tried a heat gun to get the glue soft enough so I can pull the wiring off. In the end I left the wiring where it was and just lowered the headliner to install the butyl / foil sound deadener then the foam liner on top of that.

The first thing I did was to remove the negative battery terminal. Don’t want airbags accidentally going off on me.

I started by removing all the hardware on the roof of the car: Hanger hooks, visors, visor clips, the oh-my-god handle, and the 2 light fixtures.

I popped the A pillar trims off which keeps the headliner in place. Then I removed the screws from the middle and back pillars in order to remove those pillar trims.

Once there is nothing holding the headliner in place, I pull the door gaskets near the headliner down. Then I pulled the headliner down starting from the back at the trunk. There’s a bunch of wiring connections there for the GPS, AM/FM, and Sirius antennas that need to be disconnected or the headliner stays put.

I did it the hard way, slipping material between the headliner and onto the roof. Rolling this stuff down was an exercise best made by a contortionist, but I did it.

Here are the pics:



All screws are T-15.

At this stage, that's when I got started installing the butyl layer.

Now the Noico Red closed cell foam liner.

29467


At this stage, I just put everything back.

Also, there are two wide plastic washers for the rear headliner fasteners that go on the inside. This keeps the fasteners in place when putting everything back together. Sorry, it was getting dark and I forgot to take a picture of that.

Dang, you really did one heck of a job there. I'm really excited to hear your experience after some time driving it....

So far I've done the sound deadening of all 4 doors, also I pulled the inner fenderwells and "painted" the back with rubberized undercoating spray. So far I'm really pleased with those improvements, but always in the back of my mind I wanted to do as you've done with the sound deadening the roof...

slow clap
Amazing job, man. As much as I’d love to do something similar, I’m pretty sure I won’t be able to do everything you did and just break one trim piece. Really impressive work. I’m willing to bet your interior audio space now far exceeds most of the touted “premium cabin” comforts by other luxury car makers.

Wow, just wow! Thank you for the write up. Really raising the bar! How long did it take you from start to finish?
Took like 4 hours to do the roof. At least 2 hours of that was figuring out how to get the headliner off.

Putting the material on was easy. Everything was rectangular.
