No, Mr. Hoongwai, chemical film and clear anodize are different processes. Chemical film is a conductive chromate conversion coating of aluminum. Anodizing is a non-conductive electrolytic process which creates an aluminum oxide coating on the parts.

If you want a clear anodize, the corresponding MIL spec for the clear anodize is MIL-A-8625F Type II Class 1.
