Thanks Kevin and Zac! Those photos may come in handy someday...

I started the "priming, sanding, filling, sanding and priming again" process. You can see the raw edges and bits of schmutz after the first primer run. Also, steps were manifested on the lower fuselage sides. After some putty and sanding, though...the last couple of shots show it's pretty much ready for color. I'm treating this just like a plastic model but just being a bit more gentle with the sanding process.
The only thing that didn't go to plan was that my embossing from the back side needs to be heavier as you can barely see the stab/elevator/rudder lines. I'll need to go over the wings before I skin them if I want them a little more pronounced.
Looks nice, though! Can't wait to start spraying. I think I'll mix some turquoise for the lower parts tonight and maybe give it a spray! We'll see.
Thanks for looking,
Dan
