This 50' boxcar is one of the oldest on my Miami layout (BLT. 10-74). So I decided to turn this beautiful new Athearn Genesis car into a rust bucket. I started by giving it a wash with white acrylic paint, that I diluted with alcohol (it was more lightly tinted alcohol than diluted paint). The graffity decals are from Microscale. After applying the decals I airbrushed a thin coat of clear matt paint to seal the decals and then sprayed a very thin layer of grimy brown. The rest was done with acrylic paints, a very hard paintbrush and an old cotton t-shirt.
