Installing German sound dampening pad

here is an original 1968 inner rocker.
the rocker was undercoated, painted body color white, then adroplast tar mat 3mm thick and then rug installed.
I have another 1968 that was done the same way in this area.

unfortunately, the other areas were so decomposed that the pictures would be virtually useless.
It would be great if others post pictures of there 1968 sound deadening.
i have some small evidence that the 3mm tar mat (adroplast). was on the floor as well in 1968 (or at least a dec 1967, model 1968)

Here's the floor of my '71 targa. The car was originally conda green but had an exterior only black maaco paint job


The mat looked like it was melted to the dark primered metal floorpan, no body colored paint on the metal. But there was green paint on the upper surface of the mat. This green was then covered with black paint and carpet.

Thanks, rmakosaito This is a great illustration of the tar mat for 1971.
It is clear that the 3mm tar mat is applied and it still has the smooth felt (paper) surface.
The post by flatsixer shows his 1973 with the tar mat patterned felt surface.
P.S. i am not 100 % sure that the 1973 patterned surface is not the result of the rugs that have a patterned backing may have imprinted the pattern.

Hi Bob,
It might just be the lighting in the earlier photo, but my mat had the hexagonal pattern. Here's an in-progress photo where you can clearly see the pattern on the mat to the right.

Great information rmakosito. I know that 1968 cars had a horsehair mat on top of the tar mat to help pad the rugs.
you said that your 1971 car had the rugs directly on top of the tar mat.
Did the rubber backing on the rugs create the imprint on the floors tar mat? (I actually think that the tar mat was imprinted as installed because the patterns ore so perfectly formed.)

Bob, don't you feel that the tar mat and the horsehair were part of the same product? And sadly I'm going strictly off of memory from multiple cars, but I felt that there was a tar/horsehair product that had a pattern that was on the floor of these cars (through what year, I'm not sure) and the rugs layed on top of that.

At this point I can put my hands on only an original floor 67, my 68's are located in storage, and that's the latest car(s) I currently have. I just looked at the 67, and definitely a tar/horsehair combo. Dimpling pattern appears to be from the back of the original rugs.

back in the early 1970"s and 1980"s I put rugs in about a dozen 1966 -1972 911/912.
I cant remember any of the details. well maybe a few.
my reasoning for the tar mat being under the padding on the floor is that the 1968 back parcel shelf and wheel house/bulk head areas were done that way with tar mat then padding.
the 1971 and 1973 floors shown above have the tar mat melted to the floor, but they did not use a pad, just rugs on top.
So it made sense to me that they would have melted the tar mat in order to assure that there would be no voids.
However looking at the parts book. It shows the pairing of tar mat and padding for the parcel shelf and wheel house areas, BUT it only shows a "tar mat' on the floors.
So your observation matches the parts book.
Is it possible to show a picture if your 1967 tar mat floor?
I believe 1968 would be the same as 1967.
I am guessing this because the back parcel shelf and wheel house areas are the same as 1967

here is a picture of the rear seating area of a 1968 911L Targa. clearly the tar mat was layed down and then the horsehair on top...

As usual I guess I am asking stupid questions but I asked above if anybody had tried the Stoddard product. I note Aase also has a similar product. The advertise a synthetic horsehair mat. Did anybody use one of these kits.

I'd also be interested in anyone's opinion of the kit Stoddard sells.
