Total disassembly which is easy. Cotter pin, long pivot pin, ball bearing, bearing spring and a bearing cover plate, then the mount, the board and the board decorative trim plate and two bolts that hold the decorative trim plate. Soaked all metals in mineral spirits, sanded the scratches, primed, painted and cleared. When you reassemble you need to put some sacrificial rubber or other material where the foot board and the board mount meet when the board is deployed downwards. Those two surfaces will rub and you will lose some paint and then the board mount will look yucky when the board is flipped back up. I bought some thin black neoprene sticker material on eBay. Can't see it when the board is up. Grease the ball bearing and bearing spring. All done.

Good luck
