Tracing Panel Lines With a Pencil

I developed this technique a few years ago when I was trying to find an easy way to delineate panel lines on my plastic model airplanes. The results of using a pencil are quite good. It works best with a flat/dull surface. You need to use a well-sharpened #2 pencil (or a different grade, depending on your taste). 

Carefully and slowly trace the panel lines of your model, blowing air with your mouth as you trace the lines to help remove the excess graphite from the surface of the model.

When you are finished delineating your model, apply a coat of dull or glossy clear lacquer to help seal the graphite to the surface of the model plane. The results are fantastic. See an example below.

NOTE: You can also use the graphite from a pencil to add some subtle weathering effects to your scale model aircraft. 

Sharpen the pencil to expose the graphite. You can also use fine sandpaper to create powdered graphite by rubbing the pencil tip against it. 

You can simulate areas where paint might have worn away to reveal the metal underneath (such as leading edges of wings, access panels, or high-wear areas). Rub the pencil tip gently over these areas. 

You can also use the graphite to create exhaust stains and gun soot. use the graphite to lightly shade areas where exhaust stains or gun soot would appear, behind exhaust vents, and around gun barrels. You can blend the graphite with a cotton swab or a brush to create a smoky/diffuse effect. 

Remember to seal the graphite with a light matte or sating clear coat. This will protect the graphite from smudging and fix it in place.
