DETAIL: Has anyone used Zaino Z-PC? (especially on black paint)

[mthreat]

Zaino has a fairly new product called "Z-PC Fusion Dual Action Paint Cleaner Swirl Remover", or just Z-PC for short. It uses a diminishing abrasive system to remove swirl marks, minor scratches, etc. (Rather than fill them in).

Has anyone used Z-PC on their paint, especially on dark paint?

I'd like to use it on my black paint, and then lay on the normal zaino products (Z-2, Z-5, etc). However, there's one thing on the zaino page that worries me:

I used Z-PC and now the paint looks hazy. Is this normal?
Dark color surfaces, especially black, will sometimes leave you with a slightly hazy or milky surface after using Z-PC. Z-PC Fusion does not have any fillers or oils. To make the surface crystal clear, apply your ZFX enabled Z2 or Z5 to make this milky look go away, leaving a perfect, crisp, clear, BLACK and scratch free finish.

What do you think? I'm thinking I should follow the advice and try Z2/Z5 first.
