I soon realized that only a miracle would return them to their once shiney state and decided I would just have to work with the rust and the color it made once smeared around with paint striper. Having recently drawn old tractors I figured that these would be appropriate subject matter for the surface.
After stabiling the surface I drew my tractor on. Remember that dark rusty color? Well, it definitely affects the ability to use color in the drawing. Most of the work is done with colored pencils.
The photo does not do the surface justice as the camera did not register the color differeniation very well. The piece is about 9" high by 12" wide and a bit sharp on the edges.
