Back at it! My goal for today was to spend a few hours getting the left tank prepped and ready to be cleaned and dimpled. I pulled everything apart and started the long process of deburring all of the holes and edges in the skins, ribs, baffle, z-brackets, stiffeners, etc.
After everything was deburred, then any surface that will get proseal on it during assembly had to be scuffed. Next I will dimple the skin and other parts, then after cleaning everything with acetone they'll be ready for assembly and sealing.
