Reflectivity of Aluminum

Does anyone know the highest reflecitivity of Aluminum surface, either prepared by mechanical polishing, suptttering, or eletropolishing? We have obtained 90% reflectiivity from sputtered Al film. Is it possible to push it to 95%?

Actually I think it's substantially greater than 95 percent, possible via electropolishing of high purity grades of aluminum. But the thing is, I can't remember which reference book discusses it and I'm away from the office. I think it's ASM Metals Handbook Vol. 5 under the index topic of electrolytic polishing. If you have a copy look there; otherwise I'll try to get back to you on it when I can.
