Today I primed the rear ribs for the left wing. Before I promed them I scuffed them with dish soap and a green scrotch brite pad. This was to ensure that the they were adequetly clean and degreased and the primer would properly adhear to the aluminum. The inflatable paint both has been a big help. It allows me to paint in the garage and keep the overspray under control. This will open up times that I can prime in the future and hopefully speed up the build process.
