Yah some good car wax and an electric buffer can make aluminum look very nice, And from experience, Yes the wax does stop it from corroding. Although aluminum doesnt rust, it will def oxidize if left totally un protected. They will turn white in spotsand eventually form little white flakes. The best difference is that aluminum oxide actually protects the rest of the metal, whereas iron oxide(typical rust on steel) works like cancer and continues to rust away once it starts.
