Carbon fiber is an incredibly lightweight material that possesses an enormous amount of strength given its weight. While carbon fiber is sold in many forms, one form is in a flexible roll that is often backed with adhesive. These rolls can serve as a decoration for vehicles, since carbon fiber has a fairly distinctive and unique look. They can also change the look of a vehicle without paint.
