Russ, I know how you can feel about weathering N-scale. If you make it look like a proto-photo, it usually looks just too darn dark on a layout. I've wished a thousand times for a "scale black" for Frisco deisels. Except in photos, even with weathering, black engines look alot like "black holes" on the layout. Too much of the great detail dissapears. Ah, such is life.
