Plating is the method of covering the covers with a thin coat of metal done by electrodeposition. The gold used on covers is usually 24 karat in color and uses a specific chemical process in combination with or without electricity. Plating is used to keep the metallic object from either rusting or oxidizing over time. Most gold covers are plated quite thin and some use a thin layer of lacquer sprayed over it to help protect and reduce wear. Gold plating has less durability than nickel or chrome plating used on many guitar products.
Covers can get worn from the constant wear of picks, sweat and wiping down the guitar after playing. Use a soft non-abrasive cloth to remove all the debris and moisture after use. Try to blot and gently rub the pickups rather then rubbing them hard back and forth that will wear away at the plating. Chrome plating is the hardest and most durable and next is Nickel plating that wears well but tarnishes after use and finally the gold plating which can be less durable. The plating thickness can be increased on the covers for more durability.
Covers can be deep drawn or fabricated from a variety of materials and they all react differently to the plating process. Covers can be made from Nickel Silver, Aluminum, Brass, Tin and other materials that can be plated for cosmetic appearance.
