Abstract
A golf club having a hollow golf club head which is filled with a gas under pressure. The interior surface of the golf club head is coated with a solidified layer of plastic material. The pressurized gas permits the use of thinner face plates by compensating for forces generated when the face plate strikes a golf ball. The plastic layer is preferably applied through the process of rotational molding using a thermoplastic material.
