Electro- brush precious metal plating system. This system is the same one that Midway USA uses to plate their guns and gun parts. They don't have as many options as this kit has. If you want to see this plating in action, go to the Midway USA website and click on Gunsmithing, click Metal work and finishing then video number 9 and you can see the plating in action,. The plating and the precious metals they use are the exact type that I am parting with. I got this whole kit to plate gun parts but not long after I got it I moved into an apartment. Can't have guns here. My loss, your gain. The precious metal I am parting with are 24 ct. Gold, Pure Silver. I also have Copper, Nickel, and Brass. I have enough plating to plate 24 handguns. If your plating jewelry and not handguns this should keep you in plating for years. All of the positive and negative wiring included. Various power plating engine, completely adjustable from 1.5 to 12 volts included. Also, includes extra clips in small, medium, and large. These will allow you to overcome an resistance in the metal being plated. System is actually really easy to use.
