no prob!
A polymer layer comprises long molecules that that form a hard, dense flat mesh that lies on the top of the much smaller paint molecule. Polymers are hydrophobic [lacking an affinity for water] the surface is smooth which in part causes water sheeting.
Carnauba Wax is inherently hydroscopic [readily taking up and retaining moisture] when exposed to water, wax swells and closes its pores, beading simply means that a high surface tension is present.
What most people attribute to a film surface protection being functional is the visual indicator of water beading on the paint film surface. However, all water beading proves is that high surface tension is present, just because a product creates high surface tension, (water beading / sheeting) does not guarantee the coating is actually providing real and meaningful protection
Water beading is only a sign of high surface tension, it does not automatically mean the surface is protected.
Water beading can be a visual indicator of a coating's presence. By that I mean, if your car's finish does not bead water before, cleaning, polishing and protecting, but does bead water after applying a protective wax coating, then as the beading diminishes over time and exposure to repeated washing or inclement weather, the lack of beading can be a visual indicator that the wax is wearing off.
Some Meguiar's waxes, like Gold Class wax, are not formulated to bead water well. Many people read into this that it is a product that doesn't protect well. The chemists that created this formula understand that water beading and then drying on painted surfaces can lead to problems, so they designed Gold Class Wax to not bead water.
While it's easy to explain the benefits of a wax that sheets water instead of beads water, it would appear that most people prefer a wax that beads water, if for no other reason, than it looks cool.
P.S: I cheated on that post hehehe
