Here's one of the bays after smearing proseal in the corners, but before I removed the tape.

...and after tape removal. The tape does a great job of keeping the mess down.

All that's left is to put fillets around the stiffeners. Oh and dab over the end rib doublers and install the BNC connectors and seal those up and install the fuel return fitting and the flop tube and and and.

Sigh I can't wait till these are done. I think the tanks are almost as much work as the entire rest of the wing.

I used up the last of my proseal. Gonna have to order some more. :-(
