The SD1, a much maligned car, has ventilated sills. It's wheelarches, door skins, bonnet, tailgate and rear panel rot but the sills don't.

Most 75's and ZT's now have ventilated sills :drool4:

Problem with filling sills with expanding foam is that if some unsuspecting soul tries welding or cutting the sill a very destructive fire could result.
Some of the foams are made of similar compounds to the foam that backed the tiles on Grenfell tower

Spotted the O/S/R of my ZTT is a little crispy around the jacking point area, further inspection pending.
After the whole new rear end this year, it won't be the end though!

Another offside rear
 

Mat - you might find what I've just found (see below).


On further inspection, my OSR is not as good as it seemed on first sight. I've now bent the flaky bits back with a flat screwdriver and it looks like this (1st pic below). I'm not sure what to do now because I was planning a complete rear end overhaul, including a new subframe.

I'm convinced the jacking pads are to blame for most of the corrosion - they trap water. It's not hard to tell which of these pads was in the offside rear position. :mad:

What to do next?

PS. The first 4 pics above were taken using a mirror lying on the ground - hence they're a bit soft, and might be back to front! :}
