With baby Addison coming "soon" I decided to get the right tank caught up. Installed & sealed all ribs except for the inboard most rib. I brought the tanks inside to speed up curing time since it has been <50 degrees outside in the shop. Peter dropped by after the EAA breakfast on Saturday and gave me hand sealing & riveting. What a great guy! He helped for about 4-5 hours. I also got the left inboard rib prepped . The domed / sealed plate nuts are a bit of a pain to rivet in place. I Pro-Sealed the access plate reinforcement ring & platenut to the inboard most rib... It's not called for because the cover plate covers the whole external area but what the heck, I don't ever want to have to worry about leaks around the access plate screws.
