I hung the doors, and painted the exposed heads of the hinge pins. For that, I had to mix about one milliliter each of maroon and black paint. I also sprayed some rustproofing compound in some of the body seams, such as the base of the cowl panels. This could be done only after the entire body was painted.
I need to figure out what to work on next. There are a lot of mechanical assembly steps, but some must be done before others. I will probably look into getting new window glass made locally. Then I could refinish, assemble, and install the windshield.
