Klasse All in One alone will last longer than Zaino, that is for sure. Putting Klasse Sealant Glaze will further increase the longevity of the product, as well as Sonus Acrylic Spritz...but for the ultimate in shine (lower durability), try Klasse All In One and top it off with a show car wax such as Pinnacle Souveran or P21s. This combo is simply the most famous combo in the detailing industry, especially on darker colored cars. Soon I will be getting this combo...I can't wait. As a tip, I will tell you that the key to having a sparkling paint job is not in the wax, it is in the preparation before the wax.
