I am old school and use mothers california 100% carnuba paste wax as my final step. I use mostly "PRO" products and "Mothers" or "3M". I just cant justify the money for the Z products when I get the results I do from my wax. Not knocking the line. I hear all great things about the products. I know a lot of deatiler use the Zaino line. I also know a lot of detailers and colision shops who dont and stick with whats been good over the test of time. A good pro grade buffer and a good techique and you can do wonders. My paint job was in horrible shape when I bought my car. I was able to resurect it. I guess it depends what you want to spend on detailing products. I dropped some cash on a pro grade buffer instead of zaino.
If your paint is already in good shape, then Zaino is prob the way to go. I had acid rain etching and swirl/spider webbing to cure. I needed a buffer and cutting compounds.
Doubt I helped, but thats my experience and what I think for whats its worth LOL
