Cut J-stringers to length and drilled in assembly. Time to remove bottom skins so I pulled the bottom skins for the L. wing out of storage. Removed blue plastic from the bottom and rivet only strips on the top. Deburred holes and then dimpled. Tonight I got the L. wing bottom skins done and then removed the R. wing inboard bottom skin and got it deburred.
All put together just so I can pull it apart again.
Used soldering iron to remove strips of plastic along the rivet lines only.
