This time it’s a repair panel for the seat base / boot floor.
Originally this was cut out to remove the worst of the rust, but with a repair panel in hand, and some time cleaning up the rusty floor section, I decided not to beat about the bush and cut out all signs of rust.
A lot of trimming later and the panel is ready for welding.
Bonus – photos of the painted battery box and one of the arch infill panels.
