Most common finishes: #7 Pre-buff, #8, High Polish Super 8
A #7 or Pre-buff finish is a clouded or hazy mirror finish. The grain is purposely left in the material and it is used for ornamental applications that do not require the full mirror finish, or applications that require a smooth surface preparation for coating.
The #8, Mirror finish has the appearance much like that of a glass mirror. This finish is polished directionally and easily blended for fabrication.
A true, Super 8 is a step above the traditional #8, Mirror finish. This superior mirror finish is the cleanest, truest mirror, but it is also used the least often as it is extremely difficult to match, maintain and repair. With the Super 8, it is nearly impossible to successfully achieve satisfactory results in the field.
