i have one of each at my own house... sheeting and beading....
they both dry exactly the same.... spot free....
i think , its pure water... sheeting water leaves a thick layer of water to dry out.
beading water leaves a lot of little bits of thick water to dry out...
same i think, oh and its pure water so it should dry clear.
personally i think, its the duff seals that cause spotting, or not rinsing well enough,
after all this method was introduced as the future of window cleaning, so in a perfect world it should be brilliant,
pure water dries clear.
so its either seals or dirt not rinsed properly.

gary.
