Does Zaino replace wax?
 

Just out of curiousity before I make the plunge, does Zaino "polish" replace waxing? Would I be better off just purchasing a high-quality wax, then using Zaino over the top of it (or vice versa)?

Zaino is all you need. Before you apply it, you need to make sure all existing wax/polish is off. It's worth it!

Does Zaino have a deeper/wetter shine than a high-quality wax like say Griot's Garage?

There are some awesome photos in the third generation forum of cars done with zaino. It's especially awesome with black :)

Nope. Zaino = overrated.
