Hi, I'm sorry I put new thread about Zaino Product again...
I read good things about Zaino Product and since I was gonna get WAX anyway, I might want to try out their product. but I notice they have more than one product z1-z18..etc.
and I'm little confused which one I should get. From my understanding by previous post and their site, I want to get Z-5 since my car has SWIRL MARKS on it. and Z-7 for car wash.(i dont know if I need this).
rest is my question:
1.I'm not sure if I need Z-1.
2.My car is black 93 sc400, which one should I get Z-2, or Z-3.
3.Their site recommends to use DAWN as a car wash but....REALLY???
4.as LEATHER CLEANER, should I get Z-10? or Lexol pH Cleaner.

any comments are welcome Thanks
