I've been doing a few things since Saturday, mostly slicing files for 3D printing and then printing them. As you can see, I'm also in the middle of deep-cleaning one of my airbrushes.
You may recall that I'd primed a piece "grey" and then hand-brushed a dark grey into the panel lines. I've airbrushed two different colours onto that piece to see how it looks:
It looks OK under the pale blue, but is far too dark under the yellow - I think that for lighter top colours I might need to use a lighter grey for the panel lining. I might also use the airbrush to add a diffuse line of a lighter grey around the panel lines so that the edges of panels are slightly darker than the centres. I'll need to test that in the next few days.
I also tested a couple of colours on the internal partition pieces:
|Liquid, gas cylinders, reinforced|
|Bolted, locked, plain|
|Back - gas can, gas cylinders|
Front - locked, bolted, plain
|Sealed, controlled environment|
