I cleaned the locomotive with Windex on a make-up sponge, while wearing disposable gloves. I do this on all weathering projects to remove fingerprints/dust etc. I masked the lights; windows; the speaker grills under the fuel tank and the area between the truck side-frames including the wheels. I then sprayed Model Masters flat finish. After, I used Pan Pastels (available on Amazon) to give the locomotive a lightly weathered look; to appear as if it's been in regular use and well maintained like the prototype on the right.
2431 was one of 140 such 3000hp freight engines ordered by the UP from General Electric starting in 1976. They were an upgrade of the U30C.
