Water. That's what we used to use before.
Or, you can mix clear floor wax and water.
I tried crowning glory once, but it made the flowers look like they were covered in some sort of clear glaze.
I've never used it since, on anything, and I don't get why I should.
We make sure all containers are filled to the brim with fresh water, and mist everything with warm water, and get very very few complaints, even in the hot humid summer.

The glazing was a common problem with the older milky white crowning glory product...........but with the advent of the clear product........that problem was eliminated.
However, on red flowers, like roses and carnations....especially for corsages........I would SELL that glazing as "PEARLED"
"using these miniature roses.........combined with your pearl jewelry on your black dress........especially when we have a process that makes the roses look like they are covered in mother of pearl........simply gorgeous"
sold that effect more than a few times....... $$$$ KACHING $$$$
