The rear part of the lower rudder fairing hold the tail light. I was trying to make it flat and flush so I can fit the Cleaveland taillight fitting. In that process I ended up sanding through, so now I have to add material. It was actually good as it also needed some strengthening of the top portion (picture is taken with fairing upside down). The upper fairing also got some love by sanding yesterdays flox smooth and prepping a backing strip for the VS fairing.
