The zinc galvanising is a sacrificial anode that erodes to protect the steel once electrolytic corrosion starts, usually due to the presence of water which has penetrated the under body paint or sealant. Since the sealant is bonded to the zinc, once the zinc starts to erode away the sealant forms a hollow cavity that collects more water which continues the corrosion and eventually begins attacking the steel. Some areas (like the front edge of the kidney bowls) are masked from the factory sealant gun, hence they have nominal paint coverage and begin erosion/corrosion earlier in the life of the car.

Only one way to tackle a job like this: one piece at a time. Our fabricator Oggy started work on the right rear corner, replacing the entire inner wing and inner sill with a new factory panels. Don't worry, I have more photos of the left side during the repair process to show what lies beneath.

Late model kidney bowl/jacking point next, fully welding the joints underneath first. This is what it looks like under the outer sill. Note the concertina heater tube (silencer) inside the inner sill to floor cavity.

You mean, apart from welding in full steel panels where there was once iron oxide? ;-)
The kidney bowls shown in the previous photos are the late 3.2 Carrera version which stiffen up the sill to inner quarter section and some subtle seam welding in critical areas. That's all.

Since both inner wings were so badly repaired in the previous "restoration" it was an easy decision to opt for the dual battery box version of the original 2.7RS. With the new right panel in place, all of a sudden the shell is starts to look like a real 911 again.

TRE in Calif. has done a number of things to stiffen the unit bodies on these cars. Also, a guy named Tyson (Schmidt??) has worked on some stiffening for the front part of the shell - IIRC, he was never sure how feasible that is.
Those are the types of things I am curious about. Especially since so much work is being done already.

Thanks for taking an interest guys.
The panels are all genuine Porsche. As far as I know, Dansk do not (yet) manufacture a complete bodyshell. The photos from the recent (Automechanica?) show demonstrate the panels they make in a contrasting colour to the 911 shell underneath.
