Thanks Harley !
I recently tried a bunch of different methods for weathering the rails on some Ross track and turnouts. After testing hand painting, air brushing, and spray cans, the best combo seems to be:
- Use a spray can of flat black primer to tone down the shiny ness of the rails, plastic, and ties. The primer also serves as a good base for the next step
- With a paint brush, apply burnt sienna acrylic paint on the sides of the rails, over top of the black primer. Just apply a thin coat so that the primer base shows through.
Of course, after each step, wide the paint from top of the rails before it dries. On the turnouts, I taped over the moving bits to prevent primer buildup from binding up the mechanism.
