OK, the last part of building the radar: weathering.
I did go very lightly on weathering, since these things were mostly stationary and well tended – no knocking around and muddy roads for them, ergo no sratches, paintchips and mud.
Some light filters, a dark wash, very light layer of dust, and a light overall wash of Vallejo’s oily earth on the platform; pretty much that was it.
