          have an airbrush, painting by
        
        
          hand works well; it just takes
        
        
          longer to complete the job.
        
        
          My favorite paint combo is
        
        
          to start with engine black,
        
        
          and then dust over a second
        
        
          coat of rust (Testors “rust” is
        
        
          my favorite).

          12a -12b - 12c: This is
        
        
          my approach to painting
        
        
          trucks. Left: A skewer
        
        
          through the hole of the
        
        
          side frame makes a good
        
        
          holding tool. Middle: A
        
        
          painting mask makes
        
        
          quick work of wheelset
        
        
          painting. While there
        
        
          are several commercial
        
        
          products available,
        
        
          I made a makeshift
        
        
          painting mask by drilling
        
        
          holes in some styrene
        
        
          scrap. The plastic
        
        
          protects the wheel tread
        
        
          while you spray the rest
        
        
          of the wheel and axle. A
        
        
          quick wipe of the paint
        
        
          off the axle point and
        
        
          you’re done. A side view
        
        
          of a wheel in the mask.
