After my success with painting (or colouring) my Gaslamp Alley building I looked back over my Old West buildings from Sarissa Precision and decided to paint the roof.
Looking back over a previous post back then I reflected on how to do this. For the roof I used 995 German Grey, which I did water down, to avoid painting out the etching and let it come through the paint.
I think I might add some weathering and detail to the roof later.
