Primed for Grime Boxcar

I thought we'd have a look at this boxcar that Brian Smith entrusted to me to add weathering.  Athearn kind of started the weathering for us, as this is from their Primed for Grime series of freight cars.  

This is their Northernwestern Oklahoma 60 foot Gunderson double door boxcar, NOKL 603252.  I looked on my usual sites on the interwebs for photos of the prototype car with the same number, but couldn't find any.  Does Athearn purposefully number models like that, so that we can't judge their weathering or patching accuracy?

I went ahead anyway, and weathered the boxcar in a manner that I thought or hoped Brian would be happy with.  Here's a few finished photos taken along my GTW line. I like to think it turned out well.

The numerous dark patches were already done by Athearn.  Late edit: I should also add that this is the first that Brian has seen of his box car since he dropped it off here for me.

I faded the car using my usual Concrete Gray, a bit more so on the 5 panels toward the ends, and Grimy Black on the doors.  The graffiti scribbles are done by (my) hand using red and green ink pens.

Same side, from the other end.

The "B" side shown here has more graffiti (decals).  I've created a deep scratch on the upper area of the left-hand end using Burnt Umber paint.  We can see some light rusting in a few areas on the roof.

I used Burnt Umber paint to show wear on the door posts and tracks.  Looking closely, we can also see some rust streaking from the door stops as well.  I should point out as well that I sprayed Grimy Black along the bottom and upper areas of the car.

Ready for pickup Brian !
