I finally had some time to work again and I pushed through a marathon fuel tank rib riveting session! I got through the remaining four interior ribs on the left fuel tank, and to be honest, I was pretty spent by the last one and probably should have stopped at three, but was careful and got them all in.I mixed up about 38 grams of sealant for the final two ribs in a single batch and that worked out quite nicely with not too much waste. I also used a scrap piece of aluminum sheet clamped to the workbench to mix the sealant on and that worked much better than paper or notecards or foil.
Here are some shots of all the interior ribs installed on the left tank:
