A method of manufacturing a reflecting metal surface, in particular to obtain reflectors for the lighting projector for motor vehicles. In this method a resin layer is projected onto the raw metal surface; onto the said layer of hardened resin is projected a layer containing a metal taken from the group formed by nickel, nickel-chrome alloys, alloys of the above mentioned metal compounds with aluminium, and silicon; then, if the above named layer contains less than n% by weight of aluminium, a fine coating containing a metal taken from the group formed by aluminium and its alloys at more than n% by weight, n being a number at most equal to 100, the value of which corresponds to the minimum brightness state tolerable for the metal reflecting surface to be obtained, is projected onto the layer. The object of the invention is also the reflectors obtained by this method as well as the use of these reflectors for lighting projectors.
