Hard Top Sound Deadening Question

[Gegna4]

Good morning everyone,

I have been thinking for a while whether this would be a good or a bad idea. I ordered a CoverKing Headliner for my JT. I have already lined my floor with KILMAT to try and deaden some sounds. Here's my question...

Would it be a good/bad idea to line the hard top with KILMAT before installing the CoverKing?

I was thinking I could go to Home Depot and get some extra type of adhesive to go between the KILMAT and the CoverKing, I just don't want them to sag and slowly start coming off the hard top due to gravity. Id love to hear all opinions on this!

And before I have to hear "if you wanted a quiet car, why did you buy a jeep?" well there isn't an answer, im just tackling the problem at hand hahah

Have a good one!

Subscribing for outcome. This seems like a great idea, be sure to thoroughly roll out the kilmat so it leaves as little of a profile footprint as possible. I’d likely only do the recessed portions with kilmat, essentially the exact same areas that coverking shows adhesive strips. So kilmat down, roll the heck out of it, then the coverking adhesive strips supplemented with 3M double sided body tape (autozone/pep boys) in strategic areas and I bet it stays for good. Skip any ahdhesive from Lowe’s/etc. that double-sided body tape is no joke.

Hi Gegna4!

Introduction: I'm a new Jeep Gladiator Forum member. Ordered Sarge Green Sport S Max Tow on 10/29 from Kent in Nampa, ID. I've been meaning to introduce myself to the forum perhaps this isn't the thread ....anywho.

I have the coverking cover & Kilmat sound proofing sitting in my closet waiting for my gladiator to arrive. I suggest you take a thorough reading of what a Jeeper did in the wrangler forums. I plan to do the same when my Jeep arrives.

Keep us posted on your work! I'd love to know of any "gotchas" during your implementation.

Sorry, just saw this. I installed NVX sound insulation on all of my top under the coverking.

No wind noise whatsoever.

Make sure you install the sound matting with a roller so it is properly bound to the top and you will be fine. Typically, once you install the stuff you can't get it off without scraping it off with a putty knife.

I actually used the black colored version of this matting.

I'm planning on doing this as well. Still trying to decide what heat ,cold, sound deadener I want to go with. My Coverkings is on order and supposedly has shipped.

[edit] By the way a quick wipe with acetone or xylene will remove the killmat writing on the material. [/edit]

So I did my entire hard top both wings and the rear cap in killmat, like every square inch, had to buy new compass and sxm antenna that I mounted to the cowl panels because the killmat blocked their signal.

I also finished them off with black sound absorbing paint. Honestly it looks like shit, overlapping joints inconsistent thickness, nothing IMO really bad it just looks like a guy did it in his garage.

Point is it rocks, not only does the killmat block out and make the panels far more solid for the road noise, it blocks a ton of the radiant heat and cold those panels used to ignore.

I would do it again in a heartbeat. I might snap some pics tomorrow for show and tell.

I have tried twice to cover the panels in headliner but I have quickly found out that most of the headliner adhesives contain a solvent or two that just melts the sound paint and doesn't allow anything to stick to it so yeah just rocking the rattle can look for now. Honestly as many people have been in the jeep they don't notice it.

this was the paint, prolly useless but I wanted black to cover the silver killmat so why not use sound deadening paint.

Looks good! Any reason in particular you're not fully covering the fiberglass completely?

When did you place order? Curious to see if you beat the 4 week lead time

The good news … if you put the sound deadening material in… it will make your music sounds better.
