Well this is just an "off the cuff" first try at weathering, in this case rolling stock. I used a really set of pastels. I only looked at a few pics of the prototypes, and it seems like they were all pretty clean looking?? I think it looks Ok, but I'm going have to practice a little more. I need to do a better job of making streaks down the side of the hopper. After I took this picture I spayed it with some dullcote. I'll have to wait until tomorrow to see how it turns out.
