I washed all the ribs and the rear spar with Dawn dish soap and warm water to clean off any scotchbrite residue and fingerprints. Handled parts with gloves after washing. It was too cold to put the parts outside to dry, so I put them on the living room floor and ran the ceiling fan to air dry them. Kevin is in town for the holiday's so I put him to work deburring the main spar and removing the tape/tape residue from the spar. I set up the indoor paint booth to have a warmer location for priming and shot all the ribs and the rear spar. Cool temperatures made the primer dry slower than it did on a warm day. All parts primed and ready for assembly.
