takes some practice but it's easy to get the hang of it. I did the rest
of the weathering with thinned oil washes and oil dry brushing for
the rust streaks.
“I like to spray a coat of Testor's Dullcote after each weathering lay-
er to protect it and prevent that muddy look. I finished the model
by spraying the ribs with a thinned dark weathering color (usually
Rail Tie Brown), spraying splatters on the outside hopper bays from
the wheels, and the wheel splash on the ends. I wiped the ribs
clean with a Q-Tip soaked with thinner, which leaves a nice dark
color along both edges of the ribs but not on top of the ribs.
