Since your at this stage in the restoration can we assume that your looking for the sealers that go under the paint?

Just making sure you get what your looking for at this point

So working through the pictures/areas shown above

Picture #1 No sealer used on or below the transition panel between the rear inner to cowl

In the pictures the sealer would have been applied over the firewall to cowl pinch weld in front of and behind the cowl panel edge at the forward edge of that panel that sticks upward. Green arrows in the first picture. During that application the worker could have continued to apply the sealer once he reached the end and applied it over that small panel though this is not often seen. Bottom picture shows an example of that

Picture #2

The rear inner fender panel on the drivers side to the firewall. No seam sealer was typically applied between these two panels. Later spray adhesive/sealer would have been applied over some of the firewall surfaces shown in the picture but not before painting




Picture #3

The rear inner fender panel on the passenger side to the firewall. No seam sealer was typically applied between these two panels. Later spray adhesive/sealer would have been applied over some of the firewall surfaces shown in the picture but not before painting

Picture #4

A pillar base to rocker panel. The sealant we see in your picture would not have likely been there originally and products used anywhere near there would not have the top texture for lack of a better term





More later

Nothing like last minute  :)

Added an additional picture to post #5

Picture #5

B Pillar at rocker. Often non visible along the section that is visible spot welded of the panel along the top weld of the rocker panel in the door opening. Just like the quarter panel to B pillar. You want to see those spot welds not hjdden below high fill primers and such

Along the corner seam between the rocker, quarter panel lip and the B pillar panel we typically find a very small strip of caulking applied as shown in the pictures below

Pictures #6 & #7

Rear quarter panel filler panel and trunk opening corner

Not much if any sealant in this area. Typically the edges of the corner trunk opening to taillight and quarter panels are fairly sharp and not hidden with a coat of sealants. Around the quarter panel filler panel there was typically an application (wiped with a brush or solvent rag) around the edge of the quarter panel as shown in the picture below




Wished I had cleaned this off before I took a picture. Lots of body shop dust  ::) Barely make out the wiped sealant but does show the corner trunk opening panel edge well

Pictures #8-10

Rear inner fender panels to outer firewall surfaces

Unlike earlier years there does not appear to be sealant applied with a heavy spray or with a chalking gun and wiped consistently through the full production year. Instead most appear to be sealed in areas like the top edge of the torque box or the seam between the inner panel and firewall when the sound deadener was applied, near the end of the build.

Tough angle

Like at the rear of the door opening typically no visible sealant along that edge. edge should be fairly crisp

So basicaly this area ?could? be done after paint, but before sound deadener?

It appear that on cars later in the year and around your car's production period they often/typically skipped the sealant and just used the sound deadener for that purpose applying it heavy to the top edge of the torque box to firewall seam and in some areas of the inner fender panel to firewall but not all of that seam

Believe that is what the two samples I posted show
