I am looking for some pictures & dimension's of the sound deadner in the trunk on 69 custom interior cars. My car had tar & undercoating all over the trunk that I stupidly scraped off thinking someone added it as a patch. I have one bad picture that doesn't show enough detail. Thanks for your time. George
-
Interesting topic. Some discussion here; http://www.camaros.net/forums/showthread.php?t=185813
-
Thanks for the link. That is interesting concerning under coating sprayed on inside of quarter panels. What I need is information concerning Tar paper on front floor of trunk. George
-
Oops :-[
-
I suspect someone added the tar paper and undercoating in trying to quieten the car;
My 09C (late) production Z28/RS (with custom cloth interior) does not have any tar paper or undercoating on the floor of the trunk.
-
Gents, he's referring to the trunk paper that was added by Fisher Body on deluxe interior cars.
This one's a 68, but 69 is basically the same.
Ed
-
Was that just a little something extra for sound deadening? Or did it have a specific duty?
-
My 69 has no evidence of ever having had anything like that... I've owned it since 1975-76....
Gary
-
It was designed as a heat barrier to keep the heat from the muffler from melting/deforming the trunk mat.
John has a good picture of his from his 69Z that I'll ask him to post.
Ed
-
OK Thanks Ed. Makes sense now.
-
Ed, can't thank you enough for the post. That is exactly what I was looking for. What a great site. I would appreciate seeing Johns photo also. Does anyone know if this was only on early cars because someone else with a later built car said his did not have the tar paper. From the stuff I scraped off I assume it is the same as the floor tar paper deadner.George
-
I can't locate my photo at the moment, but it's just like Ed's photo in reply #5 - all original Deluxe Interior 69's got that mastic deadener pad at the front of the trunk floor.
-
If the purpose of this was 'heat insulation' from the muffler, what is the possibility that when they changed the exhaust configuration, and added the resonators forward of the muffler, that they also deleted this material? There would be more heat dissipated forward of that point, and less heat at the muffler with that change....

Amazing...why do you think I wanted these guys out-back on the T-shirt? Anyone know if Kurt has a '67 ??? ;)

Gary / 69Z28-RS
Gary, all deluxe interior cars were provided the sound deadener( I've seen it on a 10C of 69 and is also on my 9c of 69 car).
Interesting point Ed makes that its purpose was to dissipate heat. My feeling is that the trunk floor deadener purpose was to attenuate any noise / resonance due to the rear axle and suspension in the open trunk area. The material they use I wouldn't classify as heat resistant.
Ed where is this referenced "It was designed as a heat barrier to keep the heat from the muffler from melting/deforming the trunk mat".
Thanks,
-
Steve, we (CRG) had a discussion about this a few years ago and I believe the consensus was it was used as a barrier for heat. I could be wrong. John can probably shed more light on this.
Ed
-
Gents, he's referring to the trunk paper that was added by Fisher Body on deluxe interior cars.
This one's a 68, but 69 is basically the same.
Any info on whether a convertible would be different? My 68 convertible has a piece of 'trunk paper', but it isn't located above the muffler. It runs front to back on the RH side of the trunk recess. It appears to be the same shape as the picture Ed posted. I wonder if this was simply a production mistake.
-
Jeff, can you post a picture of yours?
There's not a lot of information on these, so I can't answer your question. There's not even a part number in the P&A for them. The trunk mat, yes, but not the paper. I've got a lot of cars in the 68 DB with deluxe interiors but NO paper, so I'm not sure why some have it but others don't. Of course, after 45 years, most have probably disintegrated by now!!
I've NO convertibles in the 68 DB with these, so a picture of what you have would be most welcome.
Ed
-
Jeff, can you post a picture of yours?
Ed- I was just editing my post as you were typing. See above.
I have a NOS trunk mat I purchased a long time ago. If it needs protection from the heat, then I definitely want to put something down there. The original tar-paper type material came apart when it was removed for refinishing the trunk.

Steve, I appreciate your comments, and it is interesting that some later cars had it when mine apparently did not. My car still has the original trunk paint and trunk mat, but no evidence of anything ever having been glued in that location on the trunk floor. (although there is some deteriorating material falling into the trunk area from the hat rack area above which seems like sound deadening material?).. I agree with you that a tar-based material would be used for noise purposes, ie. 'panel vibration damping', rather than for heat insulation. I doubt it would provide any significant heat insulation..
Gary
-
My early build '67 convertible with DeLuxe trim also has the "insulator" as shown in previous pictures (not like the last post of a '68).
-

Gary
I agree - that heavy mastic pad material is similar to the mastic pads on the floor in the passenger compartment, and they were used for panel damping to eliminate "drumming" of the floor pan. Photo below shows the floor pan mastic pads used in '68; '69 was similar.
-
Can we confirm if the mastic pads were the same all 3 years and between dlx and std interiors? I think they basically are the same as the pic John posted, but the fronts in 68 and 69 don't have that notch removed. Any other differences?
I have a pic of FlowJoe's Firebird floor and it has mastic all down the tunnel and nothing under the front seats, btw.
-
Jeff68, That is an interesting picture of your trunk. Shows that your car should have had the tar paper but line worker didn't know where to put it.
Kurt, I don't have as nice a picture as John's but I have three pictures that show the Tar paper installed in my early 69 11A with Deluxe interior. The two bare areas seen, I removed the Tar paper before taking the photo. Hope that helps. George
-
One more picture.
-
Judging from the hole in the deadener for the spare wheel and tire holdown hook, Possibly there to keep the spare from creating rubbing noises or squeaks against the floor ?
-

That's what I was thinking, and since the coupe had the spare mounted differently I wonder if this was a spare tire sound deadener item rather than a heat shield. Is there any discernable pattern between LOS and NOR cars?
-
I'm reviving this thread because I'm now researching the trunk insulation pad that was originally on my 4C Norwood built 1969 RS/Z with 712 Deluxe Black (Comfortweave) interior and I'm coming up short where to source suitable replacement material - anyone solve this?

I just thought of this also as mine was destroyed during the trunk floor replacement...Joe
-
When you find out what could be used as a suitable source, Lloyd, I would like to know , as well.
-
Will-do Bentley, I'm hoping that another CRG member has a source for the material and will post their findings here.
PS - in researching the trunk splatter paint and (inside quarter panel) spray-on sound deadening processes for my restoration I discovered that most all of the photos of original '69 and '68 trunks I've seen show spatter paint coverage on the back of the seat braces however no further up than the mid point. Seems spatter coverage does vary on the braces however it's generally poor. On my car (see Post #27) there was almost no spatter paint from the factory on the seat braces.

I was racking my brain trying to remember where I found this tar material, I think it was from a company called RePops. I bought a loose bulk piece. It was much better than regular tar paper. I got some brown craft paper and glued it to the top side. I will post a couple pictures showing how it turned out and one with rough dimensions. Here is a third picture of a very nice original. George
-
Great post George - thanks, I browsed Repop's web site and they make all kinds of automotive restoration sound deadening and water shield kits. They don't make a '69 trunk insulating pad. I plan to call them tomorrow to ask about selling me some bulk/uncut material. I think the water shield may work well for the paper top. Will post once I have more info.
-
George, I’m trying to understand the small differences between your pad and the original in the photo. Is your trunk floor original or has it been replaced?
-
Lloyd, Yes I did replace the trunk panel in my car. Had too many rust pin holes. What differences are you seeing?
The water shield you refereed to from Repo's is black, not at all like brown craft paper. After the glue dried on mine I sprayed with WD40 and wrinkled it slightly, looked just like the originals I have seen. George

I needed a partial lower trunk floor replacement and the AMD pan I used had 2 notable differences vs the original factory pan. First it was missing some dimpling mid pan (similar to the dimpling around the jack hook loop) which needed to be replicated and second, the drain hole surround stampings use a shallower drop off radius (you can see these differences in the photo below you posted). So to correct this we grafted in the original drain hole surrounds from my original pan. I plan to contact Repops today however according to their current web site some of the water shields they now show use a manila colored paper. ( http://www.repops.com/product-search.cfm?ca=39 )

Jim, the AMD pan omitted dimples mid pan (as circled) and as far as I know these dimples were stamped in all 1969 Camaro original trunk pans.
-
I contacted Repops today and was told they do sell the watershield and sound deadener in bulk rolls as follows:
12'x4' Universal Watershield Material
39'x72" Sound Deadener Material
They don't sell retail direct so I'm working on placing an order through one of Repops' retailers. Speaking with their Sales Manager I was told the Watershield material is black on one side and manila on the other.
-
Lloyd I see what you mean about the missing dimples, that water shield material looks good also. George
-

George, importantly you've contributed significantly to this topic - many thanks!
-
Lloyd, if you have to buy those quantities, it would seem to be lots more than necessary to do your own; you could recover part of your cost and help one or two others here by packaging some your residue into a 'trunk package' for people who want to do the same to theirs...?

Hey Gary, good point, I was planning to use the water shield for the doors too and the sound deadner in the passenger compartment to replace the original material on the floor that I removed. I'll need to figure out how much is required to complete the car and would be happy to offer the balance to whoever needs it for their project.

It seem to me when I had metal roofs put on my house & garage they used something like this. I need to go by the roofing shop to check out what they were using...Joe

Very informative topic and had no idea there was sound deadener in the trunk for cars w/Deluxe Interiors. Much appreciated!
I laid out the sound deadener in the interior of the car over the weekend and the current kits sold do not provide material for the tunnel. I'm assuming only Deluxe Interior cars received extra sound deadener that covered the tunnel, or? It appears the material on the tunnel may not have had insulation pad, just Asphaltic Mastic only.

Hi Hans, comparing the transmission tunnel sound deadener material I removed from my car during disassembly its appears to be the same construct as the under-seat material. Yes, its mastic with a kraft paper overlay. This same material was used in the trunk. I haven't received my drop shipped order of roll material yet however I plan to re-make all the deadener panels (including the inside trunk panel) using my takeoffs as templates.
-
Lloyd, were you able to remove the trunk sound deadener in one piece? Would love to see a picture of it.
Thanks, Doc.
-

Thanks, Doc.
Doc, it did come out in one piece. If you refer to the photo in Reply #27 that's pretty much how it looks. There is an area missing around the jack hook bracket. I will take a photo of it out of the car if you're interested?
-
Lloyd, Been following your thread. Really nice work and detail.
-

I have a pic of FlowJoe's Firebird floor and it has mastic all down the tunnel and nothing under the front seats, btw.
Based on the two variations of the padding images posted, it appears Deluxe Interiors also included padding around the tunnel while Standard Interiors did not - correct, or? Also, per Kurt's comment, it appears in '69 the notch area remained while earlier models did not have this piece.
-
Lloyd, Been following your thread. Really nice work and detail.
Thanks for the feedback Kelley, I appreciate the encouragement!
-
Just curious if your cutouts are the same as the others?
Thanks, Doc.
-
Lloyd, did you ever receive the material?
Not yet, will report back when I do.

Hans, here is a photo of the interior of Mike P's Norwood 11C X11 car (6cyl, Turbo 350) with standard blue (715) interior - perfect original floors - after we stripped it in 2012. You can see there is no sound deadener on the trans tunnel.

Interesting and thanks for posting Lloyd! So it appears standard interior cars did not receive insulation over the tunnel. Did Mike's car have insulation that went partially up the firewall as well as in the picture above it only appears to cover the floor boards?
-
Wonder if D55 (and possibly M20 too) had anything to do with the sound deadener on the transmission tunnel, rather than Z87? Seems that having a section of carpet missing (factory cutout) under the console might increase noise levels.
-
I ordered some of the bulk material from Repops that was suggested for the asphalt layer of the trunk insulation however I wasn't pleased with it. Its thin, about the same thickness and construction as roofing goods and quite rigid. In fact it had a granular top coat. James G (firstgenaddict) found a specialty product manufacturer in Fresno CA who is producing some really interesting concours quality niche parts and supplies for early Mustangs. They produce an underlayment material for the back seat to trunk transition on 1969 / 1970 Mustangs that would have essentially the same function as the trunk insulation on our cars so I contacted DNO and was able to purchase a roll of the material 12" wide.
New insulation material as received beside my original

Paper side (Original on the bottom). Its a thick, oiled material like the original.

(https://live.staticflickr.com/65535/50986482846_f383467dc5_c.jpg) (https://flic.kr/p/2kFv41s)
I used the Original material as a template for the new underlayment. As the curves were ragged in places I used a flexible ruler to mark the contour.
(https://live.staticflickr.com/65535/50985670548_33c1ffcc24_c.jpg) (https://flic.kr/p/2kFqTxj)
Part of the right side curved corner was missing so I had to copy and transfer it from the left side that was in tact.
(https://live.staticflickr.com/65535/50985670523_67f47e112f_c.jpg) (https://flic.kr/p/2kFqTwT)
I used the Original jack hook bracket punch out as a template for the new cutout. I measured and cut for the correct location of the jack bracket. I used a leather punch to get a clean radius in the corners.
(https://live.staticflickr.com/65535/50986484227_88a3f0e97e_c.jpg) (https://flic.kr/p/2kFv4qg)
Once I test fitted the new trunk insulation I used 3M 77 spray adhesive on the backside to secure it to the trunk floor. I used (silver) duct tape to reinforce the jack hook bracket cutout while I was working on it.
(https://live.staticflickr.com/65535/50986484222_fe65982b6f_c.jpg) (https://flic.kr/p/2kFv4qb)
The photos don't adequately capture how very well this turned out and how similar it is to the original. Its a shame it gets covered by a trunk mat.

Does anyone know if it was also used for convertible deluxe interior cars too?

Read reply #8. Since all deluxe interior cars had a mat, that should be there...Joe
-
In post #59 I referred to material that's produced by Repops and is available in kits and as roll goods for the same application. Its the asphalt layer only so a paper top layer would need to be added (a watershield grade material). As mentioned in the post its thin, rigid material that profiles much like roofing with a granular top layer. Here are a couple of photos for comparison:

I have to agree... Fantastic work and material selection, Lloyd!

Thank you very much gents. Kudos to James for finding the vendor and material!
-
You think this would be suitable on the inner 1/4s (coupes) where there is a thickened square with sound deadened applied?

who is the vendor that has the correct style to reproduce the trunk sound deadner also was this used on all custom interior car no matter the build date

Well done Lloyd and great find James..... What a duo in action......

Dead Nuts On - this is an highly specialized product and they manufacture it for their own inhouse products - underlayment in 65-70 Mustangs. they have a number of detailing products which are very reasonably priced, this is not what most would consider reasonable, however it is correct, you really cannot tell it from original,
I am considering doing them all and doing real jute on the floor side for the footwells of the floor pans like the originals for my GTO.

I just called and ordered for myself. I spoke to Jack (very nice fella) on the phone. He says tell anyone interested! They make the material themselves, and he says they can only make it in summer as the best temperature is 85-90F... :)
Thanks Lloyd for the information!
-
I received the DNO material last night via UPS (and it is dead nuts On!).. :)
When I ordered it, I was given the option to get a 'cut piece' of 12x36 (the size Lloyd stated in his post), OR they could sent me the full piece as they make it for the same price. I told him to ship the full piece and I'd cut it. It came in at 24" x 57" (enough to do two trunk pieces if the 12" is wide enough).. So my question for Lloyd or whomever has the original in their trunk (mine was missing when I purchased the car).. IS 12" wide sufficient? If so I could provide the other half to someone or use it elsewhere in my car)... but if it really needs to be 12.5 or 13" then I want to cut it as close to the original part dimension as possible.
My thanks in advance for any/all responses! :)
-
Gary, glad to hear you're pleased with the material from DNO. Back at Reply #31, George (No Yenko), posted a good photo with dimensions of the (re-created) sound deadener pad from his car that is consistent with the measurements from my original. As shown, the rough dimensions are 9" x 34.5" which is why I ordered a 12" x 36" piece. The larger piece you received should be enough to make two. The precise location of the jack hook bracket varies somewhat so I suggest you trial fit the material first to locate the bracket prior to the cutting the hole for it. Here is a repost of George's photo:

Lloyd,
Thank you very much (again) for the information on your trunk mat efforts. With this info I should be able to reproduce it accurately enough.. :)
If there's no other places in my Camaro I could use this material, then I have half of that piece of material I could move along to someone else if there's any interest... (12" x 57" piece).

Gary, as your Z has a deluxe interior, the sound deadening used on the passenger compartment floor and trans tunnel is the same material. Are you are considering replacing that as well?

Lloyd, My car still had the original material under the carpet, but for some reason it didn't have the trunk insulation... and no idea why ?

I'm planning on replacing the original interior sound deadener with DNO underlayment. The original has broken down and smells unpleasant. I'm working on how much of the DNO roll goods are required to do the job.

I pulled and replaced my original carpet 20-25 yrs ago and at that time, the underlayment looked good (and I don't recall a bad smell!).. and it hasn't been out of the garage since then, But maybe I need to pull the carpet and do another 'smell test'?? :)

I am going to be making the trunk sound deading pad for 67/68 and 69. The are going to be vary accurate reproductions. Please PM me if you are looking for one.

Every old car has that old car smell, some don't mind it and some are even fond of it. When my youngest son was a pre-teen he used to quip "your car smells like grandma's basement". If you've ever had water problems the musty smell can be down-right foul. As I'm restoring my car I prefer a neutral to new car smell and that won't be possible without replacing the underlayment.

You think this would be suitable on the inner 1/4s (coupes) where there is a thickened square with sound deadened applied?
Bentley:
I don't think that thickened square was a stick on material. I believe they all look like that (or at least 99% of them do) simply from the way they were sprayed.
When I shot mine, I tried to replicate it, but I don't think the standard Shutz gun I was using was capable of creating such a sharp edge. Could have been operator error. I think they had a different gun that allowed a sharper edge.
-
They used a much different gun than a shultz gun and the product was thicker.
Lloyd on your deluxe underlayment does it have jute on the floor side?

Yes, the passenger compartment underlayment does have a jute backing on the floor pan side, I'll post a photo if you need one James.

In researching trunk spatter paint and sound deadener on original, unrestored cars, it seems that the process may have been something like this:
- Sound Deadener was first applied to the inside of the quarter, forward of side marker and below quarter glass, possibly before quarter was welded on?
- Spatter may not have been a single process; Seems that there was a somewhat thick, stringy dark grey/black base applied first followed by the aqua speckle spatter operation.
- Possible that a thin coat of the Lord Fusor sound deadener was applied to trunk floor, quarter inner wheel housing (trunk side) prior to the spatter operation?
Appreciate hearing what others have discovered on this topic.
Thanks!

I know that a few guys do use a 2 step process on restorations HOWEVER
Original spatter was a single step process they used an odd gun and If not mistaken a pressure pot. The paint is 2 components which are dis-similar which keeps them from mixing together.
The LA spatter must have had a thicker light colored component which causes it to "string" coming out of the gun.
-
Asphalt-based pads were stuck on the quarters (I don't think this happened all three years at both plants).
Another pad went on the floor of the trunk on deluxe interior cars.

Replicating the trunk splatter is very confusing to say the least. Some say the only process that passes judging as being factory correct is a lengthy multi-step process that only a few shops can do. We know the factory sprayed these trunks in seconds not over the course of a week. None of the spray can stuff looks the same, even the GM licensed AC Delco rattle cans are off. I noticed OER now produces quarts of Black/Aqua (which is different from the rattle can stuff they sell) which they claim is made by the original manufacturer with the original formula. They also sell a Binks 2100 gun, set up with the same fluid nozzle, needle and air nozzle, plus the pressure pot that duplicates what the factory used. Has anyone tried this?
-
any up dates for the sound deadner for custom interior trunks
-
I believe the BINKS 2100 is the correct gun.
If not mistaken - KURTS discussed the gun specs years ago.
