Stripped and prepared the panel that fits below the large window in the bulkhead in front of the entrance vestibule.  This, and the window, needs to be refitted before the outer cladding of the pillar can be fitted.  There was minor corrosion of this panel along the lower edges where it abutted various steel components.  All the edges of the panel have been treated with waxoyl to slow down further corrosion.  The panel is otherwise undamaged so good to be reused.
