Abstract:
1. A method of identifying an object comprising: providing an object having on a surface thereof at least one layer of paint; determining a unique discrete identification for the object; applying the unique discrete identification to the at least one paint layer on the surface with a UV fluorescent material; permitting the fluorescent material to migrate into the at least one paint layer, while an excess amount of fluorescent material remains on the at least one paint layer; removing the excess amount of fluorescent material from the at least one paint layer with a solvent; wherein the unique discrete identification created by the fluorescent material migrated into the at least one paint layer is visible at an acute angle to the object surface without the use of ultraviolet light and intermediary layer between the viewer and the at least one paint layer, while being substantially invisible at an angle normal to the object surface; and directly viewing the at least one paint layer at an acute angle to the object surface.
