Double anodized parts

An electronic device, comprising:

• a housing comprising:
• a first metal section defining:
• a first sidewall surface and a second sidewall surface that is non-parallel to the first sidewall surface;
• and
• a mirror reflective surface disposed between the first and second sidewall surfaces, the mirror reflective surface abutting the first sidewall surface at a first chamfer edge and the second sidewall surface at a second chamfer edge, the mirror reflective surface being non-parallel to the first sidewall surface and the second sidewall surface;
• a protective layer defining an exterior surface overlaying the first sidewall surface, the second sidewall surface, and the mirror reflective surface, the protective layer comprising:
• a first anodization layer having a first portion disposed over the first sidewall surface and a second portion disposed over the second sidewall surface;
• and
• a second anodization layer disposed over the mirror reflective surface, a first edge of the second anodization layer being contiguous with the first chamfer edge and a second edge of the second anodization layer being contiguous with the second chamfer edge;
• and
• a second metal section coupled to the first metal section with a plastic coupling member.

A housing capable of carrying operational components for an electronic device, the housing comprising:

• a metal substrate defining:
• a first surface oriented in a first direction;
• a second surface oriented in a second direction;
• a mirror reflective surface oriented in a third direction non-parallel to the first direction and the second direction, and positioned between and abutting the first surface at a first chamfer edge and the second surface at a second chamfer edge;
• and
• a protective layer defining an exterior surface overlaying the metal substrate, the protective layer comprising:
• a first anodization layer comprising a first portion disposed over the first surface and a second portion disposed over the second surface;
• and
• a second anodization layer disposed over the mirror reflective surface, wherein a first edge of the second anodization layer is contiguous with the first chamfer edge and a second edge of the second anodization layer is contiguous with the second chamfer edge.
