Someone asked me for the link to the articulated brush for inner and outer windows at the rear. I cannot find the thread anymore as it might have has a title about something else. https://www.carbuildersolutions.com/uk/inner-window-trim-draught-seal-1-metre It does not say it but this is the stuff. The base is aluminium which hold steel sections in place which is covered by the material. It means that it can be bent around corners for the rear window and stay flat rather than cutting sections out. I was surprised to find this out, but it might be that all such trim is bendable like this. So, whomever asked me the question - I was not being rude but scouring my files for the right answer. I hope this helps.
