Water based paints are perfectly fine. The vast majority of collision repair facilities are using them now, too, not just the OEMs. Any OEM finishes that were peeling were a result of that particular paint supplier, the OEM's prep/refinishing process and equipment, or both. It has nothing to do with base/clear vs. single stage, waterborne vs. solventborne, etc.... GM and Chrysler's delamination issues predate the introduction of waterborne paint by several years.
