The most common (and oldest) method. The faucet is dipped in a bath of dissolved metal that adheres to the surface when a current is applied. Pro: Offers a durable, long-lasting finish. Con: Plating is susceptible to harsh cleansers.
Physical Vapor Deposition (PVD)
The faucet is placed in a vacuum and bombarded with metallic ions that bond to the surface. Pro: Results in a very hard, tough finish that doesn't need a clear coat. Con: More expensive than other application methods.
The faucet is sprayed with a dry powder that cures when exposed to heat. Pro: Results in an even, thick finish layer.Con: Not as durable as PVD or electroplating.
