What are the best techniques for applying an oil wax wood finish to achieve a smooth and durable surface?

To achieve a smooth and durable surface when applying an oil wax wood finish, the best techniques include sanding the wood surface thoroughly, applying the finish in thin and even coats using a brush or cloth, allowing each coat to dry completely before applying the next one, and buffing the surface with a soft cloth after the final coat to enhance the sheen and durability of the finish.
