A method of identifying an object comprising a vehicle (50) having on a surface thereof at least one layer of pain (52, 54, 56), such as a urethane-based paint. A unique alphanumeric identification (30) is applied to the paint layer (56) with a fluorescent material (40) at a selected unrevealed location thereon. The fluorescent material (40) is permitted to migrate into the at least one paint layer (52, 54, 56), while an excess amount of fluorescent material (40a) remains on the at least one paint layer (52, 54, 56). Thereupon, the excess amount of fluorescent material (40a) is removed from the at least one paint layer (52, 54, 56). Thereupon, the excess amount of fluorescent material (40a) is removed from the at least one paint layer (52, 54, 56) with a solvent. The unique discrete identification (30) created by fluorescent material (40') migrated into the at least one paint layer (52, 54, 56) is visible at an acute angle to the object surface (58) without use of an ultraviolet light, while being substantially invisible at an angle normal to the object surface (58). |
