Two Week Update!
Much commuting in traffic, mild weather. Plenty of construction dirt landed on the car, so I tried to ascertain the "dirt shedding" abilities of the waxes by flooding the test area with distilled water. They all pretty much let loose of the dirt in the same, easy-peasy manner.
I also can`t really say that the 915 has attracted any more dust than the others. In my experience, 915 is bad for attracting "garage dust" and the like.
OK, on to the pics! I chose this shot because you can clearly see each test area having it`s own look-and-feel. Once wet, the tape lines are still very visible. I`m glad to say all waxes are hanging in there, and the Lusso`s beads have gotten better over time (curing I guess).
In fact, there`s been a shift in the beading rank.

Griot`s Best of Show has gotten noticeably worse. Luckily, beading isn`t everything, and the "BOS" test area is very slick, sheds water fast, and looks good.
Beading, side-by-sides:
Best beads I could get of all four:
915
Lusso Oro
Griot`s Best of Show

Interesting: in the areas outside the test area, where I haphazardly laid down wax, you can detect the holograms, but they disappear into the test areas where I carefully laid down 2 layers of each wax. The 915 is showing the holograms like muted smudges. All for now.
