Attached the right wing top skins for riveting and removed the bottom skins for access.
I then spent the majority of the time doing the fit and finish work for the fuel tank: trimming excess sealant, edge finishing, drilling holes for attachment bolts, drilling holes for nut plates in joint strip, opening p holes for #8 screws, edge rolling for fit, etc.
Finally Britt and I spent a couple of hours getting started on riveting the top skins on.
