Really hard to see with the lighting and such. While these tests provide some good information, having such small test areas makes it harder to evaluate especially on video.
I was expecting more sheeting. With the hood panel being upright as it was, beading should be minimal.
The main issue I see with that fellow's tests is that the sun might not hit all parts evenly. If the hood was rotated every week or so, that would give all the coatings a fair chance to bask in the sun. Also, there are different types of clear-coat and not all coatings adhere the same way. Still though, the guy is doing a good job on the project.
A brand new ceramic coating will sheet for about a month. Ceramics that are not regularly top-coated don't sheet water any better than traditional waxes or sealers. Many ceramics require monthly maintenance and a lot of folks now skip the ceramic and just put the monthly top-coat stuff on. Here's one of the more common top-coats https://www.amazon.com/gp/product/B00L9A0AC8/ref=ox_sc_saved_title_2?smid=A189LTAG6GCSCF&psc=1
Wash the car then do wipe-on / wipe-off with this stuff and it will sheet water for a few weeks then gradually fade away.
