yes, its not chrome, but thats close enough to mirror finish, a no paint buff could get.
The whole point is that your cant be a mirror, it would be a problem with other cars headlights at night for example. WIth out paint, there is not object for the vehicle to absorb color, thus becomes the mirror, and that only creates a reflection of your headlights or something else, that in turn, is actually twice the distance from you. its a definite traffic hazzard.
But dont ask me at what point it is ok to have a level of buff.
