With some filling, sanding and another coat of primer I am happy with the forward fuselage, at least good enough for the first flight.
I have also made a nose gear door, with both internal and external surface detail. The door plug was 3D printed. The inner surface includes mounting pads for the 3 offset hinges, with the pads set to have the hinges all aligned. Hopefully this should make installing the door hinges a lot simpler and neater.
The first attempt at the nose gear door with a foam core came out too thick, so it wouldn't sit flush with the recess in the fuselage. A second one was made using 5 layers of 9oz glass and this one fits perfectly and feels very stiff.
