I use Zaino on my black Corvette. It works great. The pro is that you get a great shine that lasts a long time. The con is that it's more work than a one step like Liquid Glass.
You're probably going to find that there are a lot of Zaino users who consider it a religious experience. I'm not in that group but I find it to give a really good long lasting shine.
