Sunlight warms the paint and evaporates the water out of the paint, leaving it hard and brittle. I'm not really sure about wind (warm wind?) but I'm sure that if you left it outside the sun would dry it anyway. But anyone else can feel free to correct this question.
No, the word paintwork is not an adverb.The word paintwork is a noun.

Paintwork is the painted surface of an item, such as a car or a building.
Wind necessarily doesn't "dry up" the rain but it helps to move around water particles, this is something people in humid areas experience a lot. Wind also helps aid the evaporation of water and other natural processes.
Wind is used to dry clothes.

Wind power does not directly require sunlight for operation. Wind turbines generate electricity by harnessing the kinetic energy of the wind. However, sunlight is indirectly linked to wind power as it influences weather patterns and ultimately drives wind movement.
Variables that affect how long washing takes to dry outside include weather conditions (such as temperature, humidity, and wind), the type of fabric, the amount of sunlight exposure, and the thickness of the clothing.
I wax my car firstly to protect the paintwork. If I don't wax it then oxidation and weathering can irreversibly damage the paintwork to the point where no amount of wax will make it shine nicely. I have seen nasty cars with faded horrible paintwork (especially red cars for some reason) and I never want my car's paintwork to look that awful. If I go to a car wash it will come out very nice with still the protective layer of wax maintaining the paintwork underneath
sand will only damage paintwork if it flicks up onto the side of the car if you want to avoid this go slowly
