    Abstract: In one aspect, the present invention is a method for treatment of a painted or glass surface so as to provide improved adhesion of a urethane adhesive applied thereafter, comprising the steps of applying a pre-wipe solution to the surface, the pre-wipe solution comprising an a hydrocarbyl substituted aromatic sulfonic acid and a solvent for the acid which is soluble in the solvent; and allowing the solvent to evaporate. In a second aspect, the present invention is a pre-wipe composition comprising from about 0.5 percent to about 10.0 percent by weight of the acid and from about 90.0 percent to about 99.5 percent by weight of solvent for the acid.
