I started early in the morning cleaning nut plates to prep them for priming. And yes as everyone says....there is a lot of nut plates.
Once the primer had a few hours in the sun to dry up a bit, I started riveting them to the seat ribs.
Riveting went fairly well. I few I needed to drill out and try again. But all in all, it went faster than I had anticipated.
I just have a small of nut plates finish off. The crotch strap brackets and a few baggage ribs needs some attention still.
