All Alloy Cup progress

For a satin finish aluminium body I have found that using light great Scotchbrite gives a good finish which I then spray with SAS maintenance fluid. After 10 or 15 minutes I wipe the excess off with a paper towel and allow to dry. This seems to give a reasonable finish which does not leave grey on your fingers. Repeat at 4 month intervals or as often as you wash the car.
I have friends who polish their ali cars and then treat them with AP50, a specialist aircraft product which is designed to keep the polished finish to improve aerodynamic and prevent corrosion.
