Returning to an old subject—what paint best matches the gray of a 79-001? I have finally done my first touch-up painting on a Workmate and my answer is Rust-oleum Painter's Touch 2X UltraCover Paint+Primer Charcoal Gray Satin. I bought and tried six other spray cans from auto parts stores, but none matched as well as plain old Rust-oleum.

Over the last few weeks I've been slowly working on a 79-001 Type 9 that I bought a couple of years ago unassembled, never used, in the original box. Unfortunately, the box had sat in a damp/wet location for a long time. As a result the rear portion of the lower frame that it normally rests on when folded had rusted quite badly, with significant pitting. Here's a small sample:

The rust was actually much worse than it looks because it continued underneath the paint in large areas. So it was a big rust removal job, but I had no reason to want to paint the rest of the almost pristine Workmate. I limited my painting to the lower rear frame, masking off all the rest.
Here are some photos showing how good the color match is. I've drawn a box on each one showing where the touchup paint is. First, from the rear, it's almost impossible to notice anything unusual.

Even close up it's hard to tell that the lower fram is any different from the leg, the side stay, os the H-frame:

On the side I had to continue the touchup paint around the corner so I masked it off vertically in line with the corner foot. Here you can just see where the paint changes.

The photos above were taken in fairly bright shade. The next one is in full sun, where the line is more visible, but still quite acceptable. Even in this situation, when you're standing and looking down at that area, the difference doesn't jump out at you.
