Sanded and prepped the front shelf bulkhead for glassing and also the two fuel strainer faces inside the fuselage. Cut four sheets of UNI for each shelf bulkhead back side (internal side) and prepared them on a sheet of plastic. Installed both on the backs of each bulkhead and spent a lot of time getting the bubbles out! Placed two layers of BID over the fuel strainer hard point. Spent time cleaning the interior of the pilot door.
