1. Sanded the lightweight filler from yesterday. It worked much better than the microballoons.
2. Located and marked the three attach locations on each side of the fairing.
3. Tightly taped the fairing in place, then drilled and clecoed the fairing in place. Checked the fit of the fairing, and pronounced it most excellent.
4. Trimmed the foam fairing caps I'd fabricated two days ago, marked where they were to be attached, then bonded them to the insides of the fairing using a flox/cabosil mixture. Clamped them in place about 1/16" from the aft end of the fairing, then brushed on some more of the resin mixture to the foam to give it strength and seal it.
