Abstract To examine the action of acid atmospheric precipitation on the light stabilisers in automotive coatings two common clearcoat types (TSA and 2K‐PU) blended with commercially available HALS and UVA were subjected to artificial weathering (Acid Dew and Fog test and Acid‐free weathering test) and natural weathering outdoors in Jacksonville, FL. Tracing gloss and haze during weathering the test results showed that the influence of acid stress on the long‐term performance of the clearcoats depended on the kind of the stabilisation system.
