Nice demo of some of the effects possible with oils. To my eye, some of the streaking looks too bold for N scale, less would be more in that case. He doesn't do much w/rust patches, but I prefer acrylics for that since heavier layers of oils would take a long time to dry. Zinc white might work better for a fade, as it is less opaque than titanium white and hence less tendency for a 'frosty' look.
