Prepped the door skins for assembly by scuffing all points that get epoxy. The next step was to epoxy some fiberglass mat to the inner door at the elbow cavity. The purpose of the mat is fill a thin gap between the inner and outer shells at that point. Otherwise you'd have a large area in the middle bottom third of the door with no internal structure. With the mat in place and before it cured, I spread an epxoy-cabosil mixture over all of the shell contact points (mainly the outer and window flanges). I then put the inner and outer shells together and clecoed around the window cutout to hold them together. I then moved the assembly to the fuse where I clecoed the door to the fuse using the holse drilled previously and used duct tape around the top edge where drilling hiles wasn't practical. I then used some spring clamps to help add clamping pressure to areas that needed more than the clecos alone could handle.
