Thanks Andy - the joints on the model are in far better condition than my own joints !
However, I had a good night's rest, and nowhere near as stiff and aching today.
There are some small areas that needed painting before spraying the grey primer for the metal finish, which included a large area at the aft, underside, which was an anti-acid corrosion coating, the radome, and some bare glass fiber antenna areas on the fin and fuselage spine, plus a white base coat for the rudder tricolour fin flash (no decal, so the colours will have to be painted).. These have been painted, and when fully cured, they will be masked, and the primer sprayed.
I was expecting the AK Xtreme metal to arrive today, but no sign yet - still, no rush, as I'll need to let the primer fully harden, for at least 24 hours, before risking the metal finish.
Should have some pics later tonight.
