Back in the day when we scraped chalk sticks to make powder (I rubbed the stick on the inside of a mini-tea strainer placed over a small wide mount bottle), I painted wheel sets with a Floquil rusty mix made with 2 parts Rust and 1 part Roof Brown. After the paint dried, I scrubbed he wheel faces with black chalk powder with a stiff, short bristle brush. Much of the chalk comes off, as adherence of powered chalk without a binder is poor, but enough remained to blacken the wheel faces. In a later Model Railroader article, Pelle recommended Model Master Skin Tone Dark Tint for the wheel faces and Model Master Dark Tan for the wheel backs and axles.


The attached photo shows (left to right) Floquil painted wheel faces using the mix above, same with black chalk, and Model Master. I didn’t see the white flecks on the chalked wheel until I cropped the photo, but it’s dust or workbench debris that shouldn’t be there. I’ll probably use PanPastel on the wheel faces painted with MM when I weather cars, but the dark MM paint looks almost black when the wheel sets are on the layout.


The best grunge modeling I’ve seen on wheel sets was done with powder on wet paint, but that’s messy. Maybe an easier way to model grunge is to spray a wet coat of clear flat on the wheel face and sprinkle on Bragdon, AIM, or other weathering powders, let it day, and shake off powder that doesn’t stick. If anyone tired that please report back, and tell us if it’s worth the effort. I’m satisfied with the MM treatment until something better but easy comes along.

Several excellent weathering articles have suggested similar methods for achieving the "crusty" appearance that form on the face of the wheel.   This involves painting the face a weathered black and following up with powders.  I have tried several methods without achieving the desired results.  One is painting the face and then sprinkling on the powder while the paint is wet.  The I ther involves letting the paint dry before applying the powder.


Any suggestions?
