Here's my second attempt at weathering a box car. I'm getting a little better at it. This is a Genesis box car to start. I painted the wheels and couplers RR Tie Brown. I also painted the trucks grimy black. The Southern Pacific herald was sanded very lightly with super-fine sand paper to remove part of the lettering. The roof was oversprayed with Grimy Black. The car was hand painted with a chalk and water mixture in a downward motion. Then I painted rust on the door and other areas with artist acrylic tube paint. The whole car was then oversprayed with Dullcote. The Dullcote removed some of the chalk, which was disappointing, so I repeated application of the chalk and Dullcote.
