Here you go - this was present on both sides, looks to run from side window to hinge area. Given a full bare metal respray in 2021, I really didn’t expect this.
I’m conscious that this has probably hijacked the thread of a different car now tho; I’m so sorry!
If anyone is local ish to Reading and would come with me to view and advise again that would be awesome, Altho I guess unlikely.
Could it be where a new roof panel has been installed? I know there was a bad sunroof previously.

That looks awful up close. Looks like the filler wasn't sanded down smooth enough before paint - can see all the scouring lines in it. It does look like the spot we were referring to where the lead should be.
As for that dark patch above the window.. no idea.
