method for preventing the formation of coating defects in polymeric coated surfaces in a coating process comprising a plurality of steps that occur prior to the polymeric coating of said surfaces and that contact organic and metal surfaces with a plurality of aqueous compositions in which accumulate in suspension resin particles released from said metal surfaces . suspended resin particles are prevented from re - depositing on the organic surfaces by converting said surfaces to hydrophilic character by means of oxidizing said surfaces prior to contacting the oxidized surfaces with said suspensions .
