While cleaning up the frame and preparing for the welding work, I decided to take advantage of the generous loan of a Quickjack from a club member to do some other updates.
First, I cleaned up and painted sections of the frame that I hadn't done during the earlier floor pan repairs. I can't fully paint the frame with the body in place, but it's at least more uniform and better protected until I can do a full refurbishment (or frame replacement).
