In any case... Zaino is a lot of work for no better benefit than S100 or NXT (IMHO) from a shininess standpoint.
However, it's not really fair to compare Zaino to plain wax from any other standpoint because it is an acrylic polymer, not a wax. It will last much much longer than any normal wax.
In the acrylic polish department I personally use Klasse products because I find them to be extremely easy to use and give very good results. After applying the acrylic polish for base shine and longevity, I put a couple of coats of S100 wax on top to give it that deep shine.
