When water forms beads on a surface, as it does on the hood of a freshly waxed car, we can say that the water is its contact with the surface because the cohesive forces are than the adhesive forces.

When water forms beads on a surface, as it does on the hood of a freshly waxed car, we can say that the water is minimizing its contact with the surface because the cohesive forces are larger than the adhesive forces

Explanation:

A waxed car's surface is covered wax which is an hydrocarbon having long chains that are very hydrophobic and therefore there is little interaction between the surface covered in wax and the cohesive forces in the water is much larger than the adhesive forces between the water and the freshly waxed car's surface which makes the water bead up to minimize the contact surface with the car's metal surface that results in limiting of the rust.
