No, it's not sticky or wet.
I don't buy colored sanding sugar. I keep white/clear sanding sugar on hand and color it by putting it in a zip loc bag and adding a few dots of Americolor in the shade I need. I close the bag and rub the sugar & color around.
There's always the possibility that they make up a mixture of colored sanding sugar and luster dust that they can pass thru a sprayer (you can spray chocolate thru a Wagner paint sprayer for a "velvet" effect). That would yield very even coverage. You could then enhance the shine by spraying on a thin coating of panning wax, maybe tempered cocoa butter, or even gum arabic.
Given that the sanding sugar+ luster dust formula comes directly from the maker's website, I have no reason to doubt it, but I'm sure they're not apt to give away all of their secrets.................
