Peen plating

Peen plating is when you make metal stuff look shiny and new by putting a thin layer of another metal on top. It's like putting makeup on your nails or painting your bike a different color! But instead of using regular paint or makeup, you use chemicals and electricity to stick a thin layer of the metal you want onto the metal you already have. This process makes the metal look pretty, and can also help protect it from getting rusty or damaged. Think of it like giving your toys a cool new outfit to wear!
