A method of coating golf equipment comprising the steps of: providing an amine-terminated component;providing a hydroxy-terminated component;providing an isocyanate;reacting the amine-terminated component, the hydroxy-terminated component and the isocyanate to form a reaction product consisting essentially of polyurea and polyurethane linkages;applying the coating composition to the golf equipment; andcuring the coating composition at a temperature of 60° C. or lower, wherein the coating has a dry film thickness of about 0.1 mils to about 1 mils. 9. The method of claim 8, wherein the step of curing further comprises subjecting the coating composition to the temperature of 60° C. or lower for a period of about 5 minutes to about 60 minutes. 10. The method of claim 8, wherein the amine-terminated component comprises a hydrophobic backbone. 11. The method of claim 10, wherein the amine-terminated component comprises amine-terminated polybutadiene. 12. The method of claim 8, further comprising the step of adding at least one an optical brightener, silane coupling agent, catalyst, pigment, filler, wetting agent, solvent, or a combination thereof during the step of reacting. 13. The method of claim 8, wherein the step of reacting further comprises adding a solvent. 14. The method of claim 13, wherein the solvent is present in the composition in an amount of about 10 percent to about 35 percent by weight of the coating composition. 15. A golf ball comprising a core and a cover, wherein a coating layer disposed about the cover is formed of a reaction product consisting essentially of at least one isocyanate and a mixture of at least one aliphatic amine-terminated polybutadiene and at least one aliphatic hydroxy-terminated compound; wherein the coating layer has a dry film thickness of about 0.1 mils to about 1 mils. 16. The golf ball of claim 15, wherein the reaction product has a cure time of about 5 minutes to about 60 minutes. 17. The golf ball of claim 16, wherein the reaction product has a cure time of about 30 minutes to about 60 minutes. 18.
