This study reveals the degradation mechanism of a typical acrylic melamine automotive clearcoat caused by bird droppings. It was found that natural bird droppings and pancreatin are able to catalyze the hydrolytic cleavage of etheric and esteric linkages of acrylic melamine clearcoats, leaving etched areas and local defects as well as a decreased appearance on the clearcoat surface.
