As an Nscale-guy, let me ask this question about weathering... How do you weather (or color) the connection hoses in the front/rear of your diesels? All the hoses on my diesel collection are embedded into the plastic snow plow and almost all are not raised enough to color each hose individually. I was going to try using a extra-fine black sharpie. The hoses seem too small to accurately paint, and chalk only colors the whole area. How do you guys handle this weathering situation?
