Got the corrections done to the upper/lower camouflage demarcation, as well as the small areas of touch-up, and the mottle - pics below show how it looks to date.
The demarcation below the cockpit could
possibly be a touch lower on the forward end, but it's more or less in line with the tip of the winkel, as on the real aircraft, and the masking tape and solid colour over the canopy area could be causing a false impression of the depth as viewed.
Either way, I think I'll leave it as is, as I don't want to risk messing it up at this stage.
Next step is to consider the 'grey' fuselage crosses. I have some Microscale decals which are nearly 40 years old (!), where the grey is a very close match for the RLM 75 paint. It's possibly a tad 'out' in actual hue, but close enough that it probably won't be that noticeable, and good enough, as this is not a 'competition' model, just another cabinet ornament,
I have used some decals from this same sheet recently, without problems, as they were sprayed with a sealing clear coat, but the first thing to do is to test one of the decals. If it works, then fine, the masks can be removed from the winkels and tail band, the model sprayed with a gloss clear coat and, when fully dry, the decal process can start.
If the test decal doesn't work, then the areas of the grey in the crosses will be formed with masks, and the RLM 75 sprayed on.
I'll find out soon, and advise on the outcome in the next up-date.
