Looks good to me. Those beads appear to be be perched on the surface where they'll roll or blow off easily. More coating-like, but not as small and tight as I've seen from some coatings like CQuartz UK.
Hard to say though without knowing how much water hit the surface and how closely you're zoomed in.

The shadows tell the tale..... great in my book!

Re: Water Beading - How does this look to you?
The beads are small and mostly round and have depth -- so great.
Curious why you are asking.
I am getting confused about which is better, beading or sheeting.

Coming from the printing industry most people don't understand that water and the wetness of water is a result of surface tension. That's why a freshly waxed or applied sealant will bead better than paint that is not protected. In the print business you want the opposite effect of water beading you want the water to lay flat and adhere to the printing substrate. Of course the chemistry is not that simple.

Water molecules are polar and thus strongly attracted to each (versus the surface that they are on). When you apply something like an oil or wax, which is not polar and thus not attracted to water, this creates the surface tension and repels the water. With waxes and sealants you are increasing surface tension and you get lots of small, tightly defined beads. As that degrades, the surface tension goes down and the beads get bigger. A coating is an entirely different story - you are actually purposely decreasing surface tension down to the point where the surface is slick enough that water just slides off, aka sheeting.

What coating is purely hydrophilic?

Anyone curious about the "bead" towards the top and just right of center?
It is no coincidence that man's best friend cannot talk.

None. But the mechanism/goal of coatings is to decrease the surface tension so much that any beading that does form essentially "slides" right off almost instantly, thereby approximating hydrophobic sheeting.
