The method involves establishing a reference decomposition product, formed by exposure to light, for the electrode position paint. The extent of damaged caused by the exposure to light is determined, on the basis of concentration of reference decomposition product of electrode position paint layer of a fillerless automobile paint. The reference decomposition product of the electrode position paint and the concentration of electrodepositing paint layer in a fillerless automobile paint are determined by chemical analysis. |
