I finished the paint-a-thon. I did all the masking for the upper body and window reveals, and sprayed them in gloss black. The spraying was tricky, because there were a lot of different areas of the car to be painted, and I had to keep dragging the ladder around, taking care not to bump into the wet paint.
After the paint dried a few hours I removed all the masking tape and paper, two big garbage bags full. The paint job looks quite handsome. In a day or two, after it has fully dried, I will hang the doors.
