Method of applying decorative layers to a steel shaft
View Patent ↗A method of applying decorative layers to a steel golf club shaft is disclosed. The method may be performed on any type of steel shaft and comprises buffing the steel shaft, applying a primer or sealer coat, curing the sealer coat, buffing the sealer coat, applying a decal or decorative layer, applying clear coat over the shaft and decal, and curing the clear coat layer. Some embodiments comprise applying a layer of base coat color before applying a decal.

a steel shaft;
a metallic protective coating situated on at least a portion of an exterior of the steel shaft;
wherein the metallic protective coating comprises nickel-chrome;
wherein the metallic protective coating includes a roughened portion;
wherein the steel shaft has a club head end portion configured for attachment to a golf club head and a grip end portion configured to receive a golf club grip;
a primer coat situated on at least a portion of the roughened portion of the metallic protective layer;
a decal situated on the primer coat;
a clear coat layer covering the decal; and
wherein the decal is located directly adjacent the grip portion.
2. The golf club component of claim 1 , wherein the metallic protective coating substantially covers an exterior of the steel shaft.
3. The golf club component of claim 1 , further comprising:
a colored base coat layer situated on the primer coat.
4. The golf club component of claim 3 , wherein the primer coat includes a roughened portion to which the colored base coat layer is secured.
5. The golf club component of claim 4 , wherein the colored based coat layer and decal are secured to a roughened portion of the primer coat.
6. The golf club of claim 3 , wherein the colored base coat layer is secured to the steel shaft with sufficient adhesion to pass 200 rubs on a rub test apparatus.
7. A golf club, comprising:
a plated shaft having a roughened portion to which a decal is secured, the roughened portion situated at least in proximity to a grip end of the plated shaft, and a clear coating covering the decal;
a golf club head secured to a head end of the plated shaft;
a grip secured to the grip end of the plated shaft, wherein the roughened portion of the plated shaft extends substantially from the grip end to the head end, and the plated shaft further comprises a colored base coating extending from the decal to the head end; and
a primer coat situated on at least a portion of the roughened portion of the plated shaft,
wherein the primer coat includes a roughened portion to which the decal is secured.
8. The golf club of claim 7 , wherein the roughened portion extends completely around the plated shaft.
9. The golf club of claim 7 , wherein the decal is secured to the plated shaft with sufficient adhesion to pass 200 rubs on a rub test apparatus.
