Preferably, contact between the surface treatment bath and the treated metal surface is established by intermittent spraying over a period of 5 to 60 seconds total. This is followed by a water rinse and drying by heating. The water soluble polymer has a chemical structure conforming to formula (I), in which (i) each of X and X represents a hydrogen atom, a C1 to C5 alkyl group, or a C1 to C5 hydroyalkyl group; (ii) each of Y and Y represents a hydrogen atom or a moiety "Z" that conforms to formula (II) or (III), wherein each of R , R , R , R , and R represents a C1 to C10 alkyl group or a C1 to C10 hydroxyalkyl group; (iii) the average value for the number of Z moieties substituted on each aromatic ring in the polymer molecule is from 0.2 to 1.0; and (iv) n is a positive integer, the average value for n being from 2 to 50.
