I have used literally hundreds of different detailing products over the years, and Zaino certainly ranks with the best of them. Zaino produces a very nice shine and the durability is absolutely incredible if applied correctly. I live in one of the worst climates in the world for car wax (snow, ice, road salt, extreme cold) and Zaino seems to plough through the bad stuff as well as anything.
You can get as good of a shine with other products, but in my opinion nothing is toughter than Zaino. If you are lazy and don't like to detail often, Zaino is your product.
Having said this, preparation is the key to any successful detailing job. I like to start with dish soap and water to clean the nasties off the car, then I clay the vehicle completely. Then I use my Porter Cable 7424 with a fine polishing compound (usually Meguiar's Show Car Glaze #7 if the paint is in good shape). After that, I do the Zaino deal, which is actually a sealant (still don't know why the call it a polish, because it contains no abrasives).
Back to the Meguiar's stuff for a minute: Really, Meguiar's makes some really good products (their professional line) at great prices. I have used products that cost way more than Meguiar's that don't work nearly as well. I played the "boutique" products game for years, and really they aren't THAT much better.
Give Zaino a shot if you like durability. I think you'll be happy.
