Why does water form into beads on a waxed car finish?

I'm sort of stumped on this one. If someone knows the answer that would be great.

Wax is like oil to water, They don't mix together.
So since they stay separate, the surface tension of the water beads it up.

Cohesion is right - intermolecular attractions (Van der Waals forces) between the water molecules cause them to stay together. The molecules on the outer surface of the droplet are only being pulled inwards, towards the rest of the water molecules, and this causes the surface tension necessary to form a bead.
