Oh what a project it! I have used Extreem Wheel Polish but very laborious. I dont know if this stuff is still available. I stopped by the Eagle One booth at a car show and the guy hooked me up with Eagle One Billet Aluminum Wheel Polish. This stuff is excellent and not quite as laborious as Extreem was. You can only polish a small area at a time and use a small piece of terry cloth to apply and diaper like cloth to remove. It is a late winter project every year to get the Centerlines ready for the warm non road salt months ahead. I do this in my basement using a waist high bench to place the wheel on. Forget about doing a good job while the wheels are still on the truck. Eagle One Billet shines and protects them like or better than new. Honest!
