There was still small amounts of water in the fuselage joints so I sprayed 99% isopropyl alcohol in all joints to absorb the water and evaporate faster.
Sprayed the exposed side of a number of individual parts with Federal Gray paint from a rattle can.
Sprayed the inside of the fuselage from wing spar to firewall with DupliColor green self-etching primer. Next will try the spray gun a got and spray the Federal Gray paint I have in two cans.
