Color Engraving on Metal Gun Slide

Step 3 Apply wax

Heat the slide using the lighter, being careful not to get any soot onto the slide. It's best to keep the lighter 1" from the surface. It won't take too much time to heat it up. Just heat the area to apply color so it's warm enough to melt the crayon. When it's hot, liberally apply the crayon, any color you like, making sure to fill in all of the engraving. It should completely cover the engraving. By heating the slide it will flow and adhere to the metal.
