Hydrophobic Coating
Weatherproof coatings for soft-top convertible roofs have a chemical hydrophobic effect that repels water. When the coating is new, water will bead up and roll off the roof. The purpose of a hydrophobic coating on a cabriolet hood is not to keep water out of your car, as the uppermost fabric layer of the hood is just cosmetic, there is a membrane underneath which provides the waterproof layer.
The purpose of this hydrophobic coating is to prevent the fabric from getting wet, so it dries quickly. The roof greening which can appear on convertible roofs requires moisture for flora to grow. When the hood stays dry, it is far harder for algae and lichen to become established.
