Finished edge deburring the skin stiffeners. Drilled, deburred and riveted the skin stiffeners to the right lower and upper rear wing skins. Found both rear skins had been stained with some substance that slightly etched into the surface. This was as received from Rans. Spent a couple of hours cleaning the skins. Had to resort to using red scotchbrite pads on an orbital sander to remoce the etching.
Layed out the building table with six 3 inch high blocks to support the wing in a level position in order to begin skin installation. Spent some time doing this to assure a true wing.
