I find most of my houses bead.
I'm glad of that because it's far more consistent.
I love it when it repels it like "water off a duck's back"

Works every time, and it's quicker.

I've never done a poor job on a window that beads in that way.
I've found a few sheeting windows have left dirt though.
When it sheets you can't tell if it's totally pure left on it, because it's just one big flood.
Takes longer to dry too.
