There's an article on weathering this exact hopper in the January 2015 Model Railroader!
and Athearn did this model/paint scheme with the patchout too !
PS : I actually just picked one up at the LHS today and though it is patched for CSXT, they didn't use the tan paint like I thought they did. If you see the computer rendering, it shows tan paint but in reality it is just black lettering over the grey paint.
