Signor Galvani has a lot to answer for!

Typical Landy job, something that seems straightforward turns into a major project!
I needed to renew one of the tub cappings on a 300TDi County 90 SW, which means taking off the roof, rear seats out etc.
Turns out to be a huge amount of corrosion under the carpet where the rear seat belt bars are anchored - steel on top, steel reinforcing plate underneath, ali sandwiched in the middle = disaster area. Other lighter corrosion on the floor is treatable with the correct procedure.
Seems to me that the best solution may be just to look for a decent 200/300 tub - what does anyone else think?
Thanks,
Anthony

Cut out and rivet aluminium. Plate in
 
Thanks, guys, that would be a simpler and cheaper solution than changing the tub and would be covered by the carpets. The other areas are the front seatbelt mountings in the front corners of the tub - will have a better look at these but presumably not just a County problem.

Galvani is the guy who realised there were electric potential differences between different metals, and that a noble metal such as gold would eat a poor one like zinc. Hence zinc sacrificial anodes on boats.

Oh right interesting :), zinc is no good for fresh water so magnesium is used.

Covering it with the carpet will be what caused the issue in the first place, gets wet then stays wet.
 
Solutions to prevent bimetalic corrosion have been around for years, both paint and materials to place between the different metals. It is just that vehicle makers do not bother.
