New strategy to assess the performance of organic coatings during ultraviolet–condensation weathering tests

•Long term cyclic tests sometimes are not enough to assess organic coating performance.•Changes in electrochemical properties within a cycle correspond to poor performance.•A stress index (ES) was calculated from EIS measurements for UV–condensation test.•ES index can provide a quick method to compa...
