I've also had excellent finishes on the above colours using ClearKote Carnauba Moose Wax as well as Natty's - CMW gives an even wetter finish.
Once the wheels are clean PB's wheel sealant is a great product to protect and to leave an excellent finish. PB's wheel cleaner, Spray and Rinse, is also an excellent strong product for shifting baked on dirt...
