The difference is not the application, but the product, maybe part of the confusion. Without reverting to the
Zaino web site, the Z products are synthetic polymers that are meant to withstand both the hot surface temperatures and the other weather effects. Wax is wax. Same as the candles you use for dinner. It melts at about 120 degrees which is not suitable to the 170+ degree surface temps of dark cars. And wax is not clear. Sure it provides a glossy finish, but it changes the color of the paint. Some like it, others don't realize it. Zaino is 99.x% optically clear. The main problem with it is the relentless pursuit of perfection means quite a few initial surface preparations steps. Many aren't willing to take the admitably long amount of time to do it (and the $100 for initial products).
But, one coat of Zaino is supposed to last 6 months on a daily driver. Many people don't just keep one coat on because the shine gets deeper with more caots and the application of each coat takes about 30 minutes.
