Its one of those things where you have to be in the mood to do things, well that time has come.
I was sick of GM1 looking way too plastic, so I have started another bulk run of weathering - fading.
Its worth noting that at this point none of the models have been spray painted at this time. All of this has been accomplished with a brush.
Once this is dried, the corners and rivet lines have had a wash of black to get the detail to 'pop" out!
Consequently this requires a slightly different approach, Gentle washes around the body cab joints and the body panels, brings out the details, and again replicates, with a grime wash, it looks the part.
Anyway lots to do, bit by bit.
