Ok.
So we are now at 1 month s/p application of the three silica sprays to the hood of my wife`s Highlander.
Over the past week, we had a couple days of hard rain and the usual driving on the interstate into Chicago for kid transportation and car pooling. In other words, regular life.
I took the car to the coin op today and sprayed everything BUT the hood with their cleaner, and I rinsed the entire car with their spot free rinse.
There was absolutely minimal sheeting of the water off the hood. I mean MINIMAL. Looked like it did before application.
On the other hand, it wasn`t really clean.
Here are the pictures of the beading.
Panel A/Product A
Panel B/Product B
Panel C/Product C
None of those beads flew off the hood when driving home (35mph). The beads were flat with obtuse angles.
I took the car home and cleaned it with McKees N914. Here is the beading on a clean hood.

So, maybe there is some protection left. Still beads, albeit not great.
Water sheeting test is below. Water still rolls off the hood in all three panels and leaves the hood fairly dry. Not as speedy as it was immediately after. But, it`s decent.
They all look about the same. Maybe B is ahead. Hard to say.
This whole experiment has forced me to think about the question: "what is protection?" How do we really measure the level of protection? Does something that protects our clearcoat have to have perfect beads? Are disorganized beads a sign of protection? How fast does water sheeting have to be?
I would say that if a last step product exhibits any of these characteristics, it is protecting the paint. A perfectly rounded bead may be attractive to us, but that does not mean that an irregular water bead isn`t a sign of protection.
