Trunk sound deadner

[69Z28-RS]

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?
