A friend of mine suggested using automobile paints (acrylic) for weathering rail, rolling stock, and any other paint application where an exact color match is not necessary. There are a huge number of colors available in automobile paints. He claims that the "micro ground pigments" found in the model railroad paints are also in automobile paints. The savings would be huge considering model railroad paints are $3-4 for a small botlle versus $15 for a pint which could last a lifetime. Is he correct?
This is not the first instance I have found where model railroaders pay a lot of $$$$ for common items. An example is a model railroad scenic material; plaster impregnated cloth. A model railroad manufacturer charges about $0.50-0.60/ sq. ft of material. A little internet searching shows a similar product in art supply houses for
0.05-0.08/sq. ft.Thanks, Steve B.
