Work has been pretty busy, so I work on the plane when I get a chance. I've been bouncing around in this section, depending on what I have time to work on. Today I was able to get the upper fire wall attached with the help of Cyndi. Applying a small bead of fuel tank sealant with the home made caulk gun adapter and applied it just aft of the flange holes....not all the way to the flange corner. This way I only had a small amount squeeze out and the clecos didn't get too messy. It went pretty smooth without too much mess.
