Prior to protecting you can use a metal polish to further clean what you have ready done. A good combo is E1 Nevr-Dull followed by Mother's "Mag and Aluminum" or billet polish. You will be amazed on how much better they will present and also "hold" the protectant used.
Try to clean the backside of the rims with every other wash with soap and water. Keeping these areas clean is a tedious task but this is what separates a "detailer" from you normal car washer.
