Benefit

Type II sulfuric anodizing places aluminum in a sulfuric bath and uses current to build up the aluminum oxide on the and near the metal surface.  This process provides corrosion and wear-resistance, and can be used as a base for paint.  The specific process will affect the coating thickness, while adding a seal can enhance the protective benefits.
