With both wing skins match drilled, I begin to prep the skins for priming. First I remove enough clecos so I can remove the blue film on the skin where the skins overlap. This will allow me to mark and mask off the skin to prep them to sand.
I wasn’t very aggressive on the top skins, however I’m interesting in trying to make this overlap section a little nicer on the bottom. Granted nobody but me will really be looking at the bottom of my wings, but I guess it’s just a challenge for me.
With the film removed and the overlap marked in sharpie, I then remove both skins and coil up the larger skin to get it out of my way. I then can begin to file and deburr the smaller skin just in case I have enough time to prime it before my fuselage arrives.
