Abstract
A method for manufacturing 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 a sealant 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 sealant is preferably applied by rotating the golf club head to coat the interior surface of the golf club head.
