===Finishing===
Finishing the work is often necessary when working in metal that may rust or where a colored finish is desirable, such as a firearm. A variety of spray lacquers and finishing techniques exist to seal and protect the work from exposure to the elements and time. Finishing also may include lightly sanding the surface to remove small chips of metal called "burrs" that are very sharp and unsightly. Some engravers prefer high contrast to the work or design, using black paints or inks to darken removed (and lower) areas of exposed metal. The excess paint or ink is wiped away and allowed to dry before lacquering or sealing, which may or may not be desired by the artist.
