Silver Plating Powder

I have used this for silver plating circuit boards. This powder is applied with a damp cloth, and rubbing causes it to deposit silver on the copper surface. The powder keeps forever, and is very solderable. It will plate on to copper, brass or bronze at least. The bottle I bought 30 years ago is still in excellent shape, and it goes a long way!

The company also has a silver-loaded conductive grease that may be useful.
