The frame having been drilled, dimpled, devurred and edged.
I thought I'd try priming the contact surfaces first and then priming the remainder of the parts once the parts were together, because the rivets are unprimed and I thought they'd look better primed with the rest of the airframe. But it's going to be too much of a pain to do it that way. So I'll just prime the individual parts and briefly prime over the rivets once assembled
