Greg -- yes indeed, I have been able to reuse masks, they often come away very cleanly indeed. These have a fringing of shattered paint coming off with them, which makes reuse doubtful. It can only be an adhesion issue, or that the bars between these panes are so thin the paint can't develop enough grip. The masking job on the 1:72 G-2 I did for RD IV last year was necessarily coarser in terms of scale representation, and seemed to work fine.
Here's the state of play: I did the radiator by drybrushing aluminium over the raised areas, then using Florey wash for the recesses, I think it came out quite acceptably:
I then fitted and painted the wing guns and mounted the propeller to the backplate:
Note the unpainted area where the sliding hood fits. I've continued to remove panels and it's maybe not too bad to salvage with a combination of careful painting with an ultra fine brush and decals if I can make them up. I'll let you knowhow that goes!
Remaining jobs elsewhere on the airframe are only the pitot, which happens after handling is done, and the dust and carbon work. otherwise it's down to getting the canopy into shape, which perforce happens before the radio mast and antenna wire can be fitted.
It'll probably be Sunday before I can make any significant inroads now, so I'll see you the other side of Halloween!

PS: Yes, I'll be adjusting the angle of that gun barrel...
