Decaling:
SP AC-4.
This engine was factory painted but the Sacramento gray was added to the boiler plus painting the cab interior a light green and the cab roof maroon. The cab roof was masked off for shooting the green and maroon. The cab interior was hand painted: being an interior and not much surface area, a nice soft brush worked fine.
Some additional nomenclature was added under the cab numbers and on the front bottom of the tender that were not added at the factory.
The satin gloss was shot over the entire engine to get a uniform look and baked for 2 hours at 200 degrees. The wheels were removed from the tender trucks as I never bake wheels.
