From a task-word perspective, it seems like nothing much done. From a tedious leve perspective, it just took a lot of time!
Started by masking-off part of the upper panel cover so I could paint the textured panel cover portion. Took it outside and painted the black part. Left on the ground in the sun to dry. Didn't want to leave on the sawhorses cuz it was breezy.
I had previously prepped the upper skin for riveting, so installed the rivets and pulled them all. Disassembled rear most portion first so I could vacuum out the chips from the drilling I did on Friday.
Installed the upper brackets and riveted in place.
