This invention discloses a method of coating an object while increasing the temper of an object to peak strength. The method of increasing the temper of the object to peak strength includes providing an object having a substantially homogeneous solution of a precipitate hardening composition; and applying an image atop at least a portion of the object, wherein temperature and time of applying the image provide peak strength in the object. The image may be applied to the object surface by dye sublimation. The object may be a vehicle wheel formed of aluminum.
