When anodizing an aluminum part, the anodizing coats best on flat surfaces. When dealing with complex shapes, or tight corners, the anodized coating may not adhere properly and a bare spot will be seen. Typically, these will be smaller than a millimeter and not noticeable unless you look very closely. IAG cannot guarantee that your part will be free of any bare spots, but we do inspect each part for consistency and reject any that do not meet our standards.
