Small up date from the few bits done recently/few weeks ago.
I got the sills all patched up and ground the welds down a little early last week.
I spent some time trying to get the new inner arch panel in, was a pain to get in and even worse again to get it out so I could get it all prepped and good to go for welding:
Welding away when I notice flames inside the car when looking through the shock topmount hole

I had left the cover in the boot area of the touring. It's pretty highly flamable! A burnt finger, some nylon drips in the boot and project touring was saved from burning to the ground
The cover is worse than what is in this pic!
Welding the inner arch in was a pain, worst welding so far, I won't be surprised to find lots of holes after I grind the welds down a little. Not fully finished it yet and didn't get pics cause it started to rain and I tidied all up. Should see this finished tomorrow and I'll move on to the next bit of rust.
Re-did my photoshoped image, I like this better:
Some pics of the inner arch I welded up, still a bit of tidying up to do on it, the fire damage on the inside :p
Inner arch:
Outer arch needs a little tidying up before paint:
Just need to finish the end of the sill where it meets the inner arch:
Started on the other sill late Monday, pretty much the same as before only this time I got the 3 pieces made up in the space of 2 evenings! I had the last piece made up, trimmed it a little and it didn't fit anymore, was also not quite 100% so doing it over.
I had a bit of a poke around the car after realising the above piece wasnt gonna fit, something to cheer me up. Found somemore rust that needs plating up or tidying, unless I find more again the end is in sight
Rear inner arch, looks to be only surface rust, luckily
Tailgate lock area, not sure what to do with this here:

Maybe cut out the same from the other touring?
Similar cracked paint/surface rust on both sides, stress cracks?
The seam for the boot rubber, bit scabby looking
Driver side arch under the battery tray:
Battery tray area, all looks to be surface rust with the exception of 2 holes on the bulkhead:
Bracket for fusebox, might cut out the one from the blue touring:
