Condition
Workshop findings:
 The painted surface of the top of the suspension strut tower appears to be poorly finished.
 The underlying metal surface appears to be poorly prepared before painting. There are coarse sanding marks
visible particularly near where the VIN is stamped.
Technical Background
1. In the production process of joining the suspension
strut tower to the adjoining structural components
weld splatter is created, and after cooling, adheres
to the metal surfaces. When the welding process is
complete these surfaces are ground and sanded to
remove any welding splatter that may have been
deposited on the metal surfaces. In some cases
this process was not as refined as necessary and
visible scoring may appear through the painted top
coat (Figure 1).
