The hood on the Z06 Commemorative Edition model is made from an advanced carbon fiber composite. Under certain lighting conditions, the carbon fiber has a faint woven appearance and can be seen through the paint, but not felt. It is most obvious when viewing the reflection of an object in the surface of the hood. The edges of the object in the reflection will appear slightly jagged, due to the woven carbon fiber material. This is normal. No special care is needed.
