Continued with priming. Painted the beige primer for the first time, went on fairly easy but picked up some dust during the dry cycle. Painted the flat black in the landing light compartments. It is a little rough due to dust, but nobody will ever see or feel it. Looks good though.
I then continued with prep and priming of the remaining parts. Didn't finish, so plan is to continue tomorrow. These priming sessions are physically difficult. I need to find a better way than scuffing.
