Ahhh, I see the "debate" on the different products lives on.
I say, "to each his/her own."
I too own a black Camaro, and personally, I swear by Zaino for it. It is NOT a wax, but a polish. Through "layering", you can really diminsh the finer blemishes. It is also important to use the proper "towels" for drying and wax/polish removal.
I detail as well, and on occassion, I will use Zaino on a customers car. Every time, when to owner comes to pick up their car, they're amazed. That's not to say Meguires, or any other product isn't good (I offer Meguires as an alternative), but for my personal cars, nothing beats the ease of use, the durablilty, or shine as a result of using Zaino.
