Aluminium continues to be the material of preference in automotive engineering. This lightweight, extremely stable and easily processed metal is not only used in bodywork, but also in many add-ons, such as covers and trim strips. Anodisation enhances its positive properties.

The aforementioned benefits of anodised aluminium are particularly useful when it comes to coloured or black components. Although the anodic coating can be dyed directly, the resulting surface still fades over time due to weathering. A protective, weather-resistant paint was necessary, since the anodic coating prevented solid bonding with the paint.
