Thanks again Bloggard.
The great thing with Sci-Fi, & to a lesser extent Fantasy, scenery is
I can leave them by the side of the Workbench, then when I have
a little paint left over (Red in this case) they get it. The weathering
is a mixture of thinned washes (making that last bit of paint go further)
and then dry brushing (normally from a Match-pot).
