If you've a water leak, that might be more of a priority
Not for this car, it'll be scrapped if anything fails (*) which I can't repair free / cheaply by myself before the next MOT (Nov) and it won't be presented for the next MOT anyway, it's served it's purpose now
* Including catching fire through a short circuit, acts of God, Perils of the Sea and Air, acts of terrorism, freaks of nature etc etc.
Agreed the only long term / car preservation solution is to fix the bulkhead rust issues that all these cars are now seeing so I guess i'll be looking into that on at least one of the other two over the summer period to see if they are suffering and what can be done. I also had the drivers door card off to check in there and that was quite damp (heavy rain last night) but accessing the blue wire in there is limited.
