Floquil 110033 Railbox yellow: chosen to closely match the Scalecoat decal color used for large "Santa Fe" lettering on hood sides. This yellow was mixed with Floquil Hi-Gloss and Glaze to give a smoother finish for applying decals.
Scalecoat 2024 Santa Fe blue: chosen for its glossy finish fo applying decals. Applied over the masked yellow.
Floquil 110144 Platinum Mist silver: applied to truck sideframes and some details.
Floquil 110010 Engine black: applied to frame, fuel tank, and some details. Mixed with Floquil Hi-Gloss and Glaze for smoother finish.
Floquil 110136 SP Scarlet red: brush-applied to some details.
Microscale 87-369 Santa Fe SD40-2 Snoot decals: chosen for its good yellow color for hood side lettering, and long-striped nose heralds for following notch nose contours.
Weathering was done with a combination of airbrushed beige (dust) and dark gray (smoke), and dry-brushed brown (rust) and black (oil, grease).
Next, careful measurements were taken from the shell to determine the dimensions of the desired warbonnet outline, based on prototype photos. Carefully free-handed curves were next drawn on the tape-on-wax-paper using a mechanical pencil with a fine lead size in order to get a sharp, clean sketch. An Xacto blade was then used to cut out the warbonnet shape from the tape, which was then peeled off the waxed paper and applied to the model.
A small jeweler's screwdriver was used to work the edge of the tape down around the details on the shell to prevent paint leakage.
