To be honest, I cannot tell the difference between the look of waxes if they are put together side by side on the same panel. Even carguy can't. It's too subjective and hard to tell. Even some Z-users claim that they cannot see the difference between their Z'd side and a freshly painted side.
On the other hand, some things that can’t be noticed side by side are more evident in “the real world.â€� For example, take the “glow-effectâ€� Paste Glaz has on silver cars, the “depthâ€� of Klasse, and the reflectivity of Zaino. It’s hard to describe the phenomenon… you just notice it.
But things like durability, water-beading (or sheeting,) and slickness are much more obvious with waxes or sealants. And, please, let’s not forget surface prep!
