Again this is just loose fitted together resting on its belly (no landing gear) with some TT models for scaling.
I probably do two coats of the thicker surface primer and a 3rd/4th for any trouble areas to get a good smooth surface then a final spray with finer finishing grade primer and 1000grit buff down and we should have a good surface finish. I also have to finish some of the trickier areas (like the intake ribs) using a dremel and buffing bit since there isn't enough room to work with sand paper or a needle file.
