ACID RAIN DESTRUCTION OF AUTOMOTIVE TOPCOATS IS A SERIOUS CURRENT PROBLEM. THIS WORK DESCRIBES TECHNIQUES OF ANALYSIS OF ETCHED SAMPLES FROM THE FIELD AND THE RESULTS OF THESE ANALYSES. FROM THESE ANALYSES, A DIFFERENTIATION OF WATER SPOTTING AND ETCHING HAS BEEN ESTABLISHED. LABORATORY TESTS HAVE BEEN DEVELOPED TO MIMIC FIELD FAILURES. A SERIES OF STANDARD COATINGS WAS TESTED AND A CORRELATION MADE BETWEEN THESE TESTS AND SELECTED EXPOSURE SITES. FINALLY, A COMPARISON IS MADE OF THE NEWEST AVAILABLE COATINGS WITH IMPROVED ETCH RESISTANCE.
