How to make a Bev-Bel PS Covered Hopper:
1. The bottom of PS styled hoppers for Chessie are black not yellow. Paint the bottom black.
2. Assemble as per the instructions. Make sure to glue the weight in there really good.
3. Weather with a dark wash. Overspray with dark grey overall and tan along the bottom. Use an eraser and erase the paint on the vertical ribs that are all over the car. This really highlights them. Next use pastels or drybrushing to streak white down the sides. This represents the spilled load.
