Harry,
I am don't know the actual physics behind the process of water beading, it
has some thing to do with surface tension of the water, and how the car
finish holds onto the water molecules determining the size of the water
droplets. The less surface tension on the car finish, the less it will
holds onto the water molecules and thus, the larger the water droplets
will be before their molecules pull apart. If the car finish is pitted
the surface tension of the car finish will be so strong it will not allow
the water to bead at all or the beads will be smaller.



Those that are familiar with cleaning optics or glass know that an
indication that the surface is truly clean is that the water sheets, rather
than beads.

Eisboch,
As I said, I am my knowledge of physics is poor at best. I am curios
why a car's finish that is as smooth as glass beads and a car that has
not been washed or waxed in years the water always sheets.

I am not familiar with any wax or polish that does not bead while just
applied and starts to sheet as the surfaced is pitted. Is there one you
find to be better than others?
