While I had some train time this afternoon I decided to take a first try at weathering, I selected a UP Auto Parts boxcar that was nice and shiny. While it would be feasible for my era it was just way to clean, when I lived in Mankato MN I saw one just sitting in a metal recycling location a few years ago well rusted (shortly after I spotted it, it was cut up as scrap).
Another reason for choosing this item was that while the UP runs in the area of my prototype I could easily do without it should weathering go wrong, add that to me having the mental image of a prototype and it was a good start. Of course the camera really pulls out the areas that could use some grime, for this stage all I’ve used is a floquil rust pen.
