Primed skin surfaces where they contact the substructure.
Installed electrical conduits and wire. Four wires for Aveo Powerburst lights, three wires for potential electric trim tab. All wires #22 Tefzel. Used a thermal wire stripper to prevent nicking the small wires.
Cleoco'd skins in place and riveted top skin. Had about 50% of the CCC-42 rivets on the leading edge needing attention due to mandrels breaking off "proud". Even with a snug fit on the rivet hole and minimal rivet gun pressure (sometimes took a couple of seconds to break) still have the mandrel problem. Most mandrels were driven back into the rivet with a drift, only a couple finally needing Dremel attention.
