I have the washes I ordered, and have added them to the spare bridge rear section I have been using to test the paint.
I now know that this will have to be done after the filter layer, and am kicking myself accordingly. It's raining again today, so I can't go out and put that on.
So in the meantime, here is the miniscule amount of progress I have actually made.
The four washes with the part I am testing on. Black, Dark Grey, Grey, and Light Grey.
And the effects on the part. Again, from left to right, Black, Dark Grey, Grey, and Light Grey.
The one I am happiest with is the Dark Grey. For some reason the Grey seems lighter than the Light Grey, although this may be remedied by repeated applications, I want to do it in as little passes as possible.
The Black just seems too dark for application over the filter layer, and I now don't really want to muck about doing that, then the filter layer, and them maybe having to re-do some of the wash.
I may use some of the Light Grey in the hangar bays, to make it more apparent that they are brightly lit, or I may add some really thinned down Black to add stark shadows.
Please let me know your thoughts on this, am I doing the correct thing?
EDIT:
I applied the washes separately, Light and Dark Grey in their respective areas first. I gave it a few minutes, then moistened a cotton bud with the flow improver, and wiped it across the details. This removed any wash that was stuck on the raised areas, and by going across the panel lines rather than along them was able to keep them with the wash in them.
