Our Alcoa aluminium wheels are 10 years old and needed a good polishing. I had polished them before by hand but that wasn't doing it any more. Got after them with the official stuff and they look much better. About 5-10 minutes each after they are on the ground so you can get at them.
I used Zephyr products. A 10 inch wheel kit with polish bar, 2 inch extender and safety flanges. Links below
