1. Marked 5/8" out from the fuselage skin and the same distance up from the HS skin, and marked this with a Sharpie. I then ran some 1/8" fine-line tape along this line to represent where the future edge of the fairing will be. Made a mark on the fuselage 1" forward to the HS leading edge, then another 3" up on the leading edge of the VS. Connected these two points with a nice gentle freehand tape curve.
2. Finished taping the VS/HS junction area with clear packing tape.
3. Applied one layer of white Loctite sealing foam across the taped area. Waited three hours, then applied a second layer. Tomorrow, I'll start carving the foam into a nice fairing shape, and it will be the base for my fiberglass and carbon fiber layups.

4. Sanded the micro on the VS plug, then applied some filler micro to some low spots.
