Disclosed are coating apparatus and coating methods to uniformly coat complex objects. The coating apparatus comprises first, second and/or third gimbals connected to rotational mechanisms to allow rotation of the gimbals around or about first, second and/or third axis. When three gimbals are used, an object holder is connected to the third gimbal. When an object is present in the object holder, it can be immersed in a coating solution to form a coated object. After removal from the coating solution, the coated object is then rotated around or about two or three axes which produces a multidirectional centrifugal force which causes the coating solution to spread evenly over the surface of the object to produce a uniform thin film. Coating methods based on the forgoing are also disclosed.
