Here are the seat ribs after riveting them together.

I used gray Marhyd self-etching primer on the parts that will be visible from the cockpit, and I tried a marine zinc-chromate on the other stuff. I didn't get good adhesion from the zinc-chromate, so I probably won't use that on too much else.

I don't have that much more work to do on the fuselage parts before I need to get a jig set up. Once I finish the firewall (F-801) and wing carry through (F-802) I need to get the garage ready for the fuselage jig.
