First thing I did this morning was fit the NACA vent to the left forward side skin. That only took 10 minutes or so. Then I cleaned and primed all the skins that I finished preparing yesterday. As is usual with priming, it took a good half day for only 3 hours of actual 'man effort'. Still, the job's done and tonight I might see if I can make a start on the remaining items (baggage ribs, angles, etc).
