Fuselage side skin riveting continued

I got some new tools to try to get to all those side-skin rivets, and that was immensely helpful:

New riveting sets and bucking bars

We finished riveting both mid fuselage side skins, and the aftmost part of the forward side skin (where it's very annoying to rivet due to the large wing attachment bolts/nuts):

Riveted left mid-fuselage skin

including all the bottom rivets that get done in this section:

I installed the rear seat vents:

We then installed the mid cabin decks, and for bucking those rivets, we had someone inside the airplane for the first time!

We also performed a bunch of smaller tasks, like riveting the nutplates on the forward cabin floor panels:

We applied sealant (Firebarrier 2000) between the firewall and the forward side skins before we rivet it in place:

Firewall/side skin joint all sealed up!

Since we were playing with Firebarrier anyway, we also sealed up the gaps in the firewall recess:
