I put an extra thick coat of primer (still translucent thought) on the forward floor area since this may see extra moisture from people getting in with wet or snowy shoes. I masked off the area in the front so that the firewall sealant can stick to the bare aluminum.
Here are most of the other components after being primed. I primed the longerons out in the driveway balanced across two sawhorses.
Here are the longerons and outboard seat ribs installed. I also got some of the deburring on the forward floor done.
