Hello, I just purchased products for doing small jobs that are in the Brass kit. 4oz solution, Brush, Wads, etc. I couldn't see buying the $15 power supply as I already have a variable DC power supply (0 to 40 Volts, at up to 1 Amp).

What Voltage will I need for Brass Plating? Will I need different voltages for different base metals? I also bought some nickel plating solution. Same Voltage??
