5th pass fairing the port bottom panel

This makes five passes on the port bottom, and I think it will need no more fairing other than when the beach bumper is done. Note that I also brushed on a thin coat of clear epoxy on a few other high spots that were getting cut into more than I wanted. On the final sanding, that thin layer should sacrifice itself so the glass does not get cut into any deeper, and save me another patch job.
