Sealants that don't bead?

[allenk4]

Sheeting is as much how you introduce water (and the amount of it) to the surface as much as the behavior of the water itself. in my mind....

In my experience, a surface that is dirty or contaminated with surfactants does not "bead" and the water evenly distributed itself on the surface as a "sheet"; regardless of the method of application or volume. A misting from a spray bottle, strong area.from a hose or laminar flow from a hose all produce the same "sheet" of water on the surface

I think PiPUK's explanation explains the difference of how we are each looking at the "sheeting"

Great explanation PiPUK

Agreed!

On one of Larry Kosila's podcasts with Jason Rose they talked about how a bunch of tiny water beads can act as little magnifying glasses. Whether or not this is true I don't really know, but this is why I'm asking this. Any input from you guys about the "magnifying beads" is also appreciated.

It's true that water beads can act in the same manner as would a magnifying lens. If nothing else: ASTM, ANSI, and ISO testing protocols have shown this relationship.

As such:
It can get really warm at the bottom/(contact angle area) of a water bead.
Given enough time and "warm & sunny conditions", many LSPs will eventually succumb to the heat that'll be generated by and through the water beads down to those highly warmed-up points-of-contact.

Water-spotting and water/etching often is the result if the water is not removed before LSPs do succumb (melt, fracture).
