1. Sanded out yesterday's microballoon filler. (I'm pretty sure I'm done using micro as a filler on these fairings, because it's too hard when it cures--and therefore tough to sand.) 2. Next, I did a lot of fine, detail sanding, including at least three hours of sanding along the electrical tape lines against the windshield glass. I tested my edge sanding technique by pulling back a bit of the black electrical tape at the lower radius (first photo). I was pleased to see a consistent radius and very thin edge along the glass. I think I MIGHT be able to sand some more of the already tiny lip with a tiny piece of fine sandpaper, used very carefully. My ideal dream would be to somehow sand this lip to be nearly unnoticeable after it's painted. 3. Sanded the blend line at the bottom of the bottom fairing. I think I now have this area very close to perfect. There's still a small lip there, which can be felt with my fingertips. I'll see how I can best address that. 4. Filled all low spots and imperfections on the top fairing with body filler.
