I decided to try Gtechniq C5 Wheel Armor instead of Armorall due to longevity claims (should last up to 9 months) I've treated my ZCP wheels inside and outside before putting them back on this spring and so far, I'm very impressed with the results. The wheels are not getting dirty as they used to (especially the front one) and they are very easy to clean with just a regular car shampoo (no wheel cleaner is required) and the water is still beads pretty well after 2 month/4 washes
Here some YouTube video
