Painting Gold on My Pan Am Maine Central Heritage Locomotive Drawing

Here I am painting the gold on my Pan Am Maine Central Heritage locomotive drawing.  When painting a color such as gold against a dark green back ground, it is important to not be afraid to let the gold go a little beyond the edges of the stripes and logos.
Once the gold is painted, the over spray of gold will be trimmed with a fine-tip dark green pen.  Gold will not be seen underneath the darker green trim.
Painting gold past the edges and then trimming up to it with green will reduce the amount of white paper that shows through the drawing.  This will make your finished locomotive truly stand out.  Enjoy drawing trains.
