Looking for pics of Dynamat / Kilmat installs

[josh72ooh2]

My car is in the middle of body/work and paint and I'm thinking this is a good time to install sound deadening material while everything is apart. 

I ordered some Killmat from Amazon. 

 

I'm looking for install photos for inspiration.  I plan to do the doors, rear quarter panels under the windows, and under the rear seat.   Are people making cardboard templates to fit perfectly into some areas? Or just cake it on..?

If you go into the Dynamat website you can see the precut kits that they make for the 2002. It will show you where the Dynamat should be placed.  It is not necessary to cover every inch of a flat panel for it to be effective.  Dynamat is super effective at making the car feel more solid.  For sound attenuation a layer of dynaliner over it makes a world of difference.

Thanks. I am going with Kilmat because it is cheaper but the Dynamat photos help.

After using a lot of them for different vintage bimmers, I prefer hushmat as it’s made in the USA and doesn’t have as much of the outgassing odor that the cheaper Chinese Amazon brands do.

There should be a bunch of reference photos if you search a bit.

 

You can find some here, along with some template examples.

then buy it here, i've happily used the amazon basics and a couple of others

My $0.02

I’ve used Siless and noico exclusively the last 5-6 years. Both are available on Amazon. They are great quality. No different from the expensive stuff. 
I use noico 80 mil then a noico red  over that. Might be overkill but it will lessen the cabin noise significantly.  I work on a lot of V8 American classics where the excessive noise can ruin a long ride so it’s a must. 
Siless has been great too. The hybrid is a very nice look.

I made cardboard templates for any Dynapad area - the rear, side panels, deck, and door panels in my case. For the floor itself, I opted to use DynaDeck because I wanted to have access to the floor pan in the future just in case. I sealed the floor prior by plastic button blasting it clean, raptor anti-corrosive primer, seam sealing, and tinted raptor as well.

great timing I'm right here with mine too. thanks folks.

I found that for the deadener (Dynamat et al) you can just flop it up there with the backing on, and use your fingernail to trace your shape in the foil. Then trim to shape and roll it on there. Saves time over templating everything. 
 

Since my M20 is deafening, I did a ton of research on sound insulting.  Where I landed is on a three layer system.
 

-After you get rid of all the factory tar, deadener goes down at 30-40% coverage. Mostly placed center panel so a knuckle rap doesn’t make a “BONG!”…more of a muted thud.  A 36sf box did the whole car. 

 

 

-Next layer is 100% coverage of closed cell foam. Noico or Siless sell 4mm with adhesive backing. Goes down easy. I used ~40sf. 

 

 

-Final layer is the actual sound barrier, 1lb/sf Mass Loaded Vinyl. 100% coverage with overlapping seams.  I covered the tunnel, under rear seat, and rear seat back wall.  I used just under 40sf

 

 

I also did Dynamat and Mega-Zorbe foam in the doors and under the roof. Hood and trunk got Dynamat and BoomMat. 
 

Lots of work, but definitely knocks the sound levels down.  Factory tar was just over 40lbs into the trash, everything I just described was 63lbs. Not a terrible gain.

I used 80mm Kilmat on the 76, easy to install, but get a roller kit! your arms will get tired! Placed it over the tar where the metal and tar were in good nick, driver's floor was replaced. Used two boxes (72 square ft), did the whole cabin including doors.

Thanks!  I am seeing 2 approaches.  One is to coat the whole car with sound deadening material, the other is to be more strategic.  I'm not going to to crazy with several layers but I do think that while the car is apart, I'll add some material to help insulate it a bit.  Kilmat arrived today as well as some Amazon rollers.

Remember that deadener is not sound proofing. It is meant to reduce resonance in the car body rather than actually impede sound transference.  It makes a big difference in rattles, buzzes and boomy sounds, it also makes a big difference when the sound system gets big.  Won’t do much against exhaust or road noise though. 
 

Food for thought.

While your car is apart you might also want to think about temperature management.  I sprayed my footwell and transmission tunnel with a ceramic compound that is designed to reflect heat before sound barrier.
