Rotating applicators are disclosed. A disclosed example apparatus includes an inlet to receive a surface coating to be applied to a surface of a workpiece, a shaft having a fluid channel extending therethrough, where the fluid channel is in fluid communication with the inlet, and an applicator coupled to an end of the shaft, where the applicator has an opening in fluid communication with the fluid channel. The apparatus also includes a pump to cause the surface coating to flow from the inlet to the opening, and a motor to rotate the shaft while the applicator dispenses the surface coating from the opening.
