The long rock wall is an important scenery feature on the HO scale Winter Hill Quarry Branch project model railroad. Now that the Hydrocal castings are in place, Model Railroader
associate editor Cody Grivno will paint and weather the castings so that they look like real rocks. Cody uses a variety of techniques for the project. He'll show you how to paint and weather the rocks using an airbrush, paint washes, and drybrushing.
