Gel coat oxidizes and it likes to have wax. It's rather porous, and it dries out. If that wax coating is not applied, there'll be a powdery substance that will come off on your clothes and your hands. The wax will also help reflect the light and prevent damage from the sun, which is its worst enemy.
