White and yellow pencils
          
        
        
          The best white pencil for adding chalk marks is made by
        
        
          Prismacolor; the number on the pencil is PC938.  To be hon-
        
        
          est, the yellow pencils don’t do a great job, and you could skip
        
        
          them all together. The important thing is to weather some of the
        
        
          white pencil marks to age them, and have some contrast to new
        
        
          marks. I use white and yellow pencils where a conductor, engine
        
        
          foreman, carman made chalk marks on a steam-era car. Look at
        
        
          vintage freight car photos to see the variety of numbers and let-
        
        
          ters used by different railroads. Put one on, and gently rub it off,
        
        
          then add another next to it, to show the aging process.
        
        
          
            Oil paints
          
        
        
          I use mostly black and brown to denote oil and grease. Mix a little
        
        
          with mineral spirits and dab around the journal boxes to show
        
        
          there the carman added oil. I also put some on the door latches
        
        
          and along the lower door
        
        
          guide where a carman would
        
        
          have greased these areas.
        
        
          
            Conclusion
          
        
        
          I hope this short introduction
        
        
          into weathering inspires you to
        
        
          get started on your fleet. The
        
        
          techniques I use are very easy,
        
        
          they just take a bit of prac-
        
        
          tice. In no time at all you can
        
        
          weather your cars like a pro. So
        
        
          jump in and get started.
