I am starting to do a lot of research about Custom Painting, Weathering but cannot seem to find a single thing about painting the wheels of the locomotives. I recently had a Kato F40PH Custom Painted and Weathered by a friend of mine. When looking at the model everything looks awesome, but then I SAW the shining wheels! I want to paint them so it gives a more realistic appearance. I know at least this much, Don't paint the Wheels where it makes contact with tracks. But other than this, it's beyond me. Currently I have 'Rust' from floquil, would this do the trick? I am planing to just paint by using a brush. Any Suggestion, pictures or comments is greatly appreciated! Dan T.
