If you want a simple answer....
I've been using Auto Armor on my GN for the last 9 years, and my finish is still gleamin'.
Meguiars products (like their swirl remover, etc) are terrific in combination. But if you are just looking for a good wax (and it's difficult to find a wax that works well on this black finish that doesnt streak), then Auto Armor does a fine job, IMO.
