In this paper the relevant mechanical and optical measuring methods (mech. Profilometry, wave‐scan, Autospect) for studying the surface structure of painted and unpainted samples will be presented. The various methods were discussed and compared in the first part of the paper, while in a second part an example concerning the influence of substrate roughness and baking position on the final topcoat structure will be given. A third part presents a study on deformed and undeformed substrates of different sheet type and the effect on topcoat appearance. In addition, a comparison of two paint systems will be shown.
