Probably more so than the commercial stuff, which should contain

Which should control or reduce much of the pitting possibility.
Also to consider is that the commercial solutions are specific for
each of the metals, and you are trying to do it with one.
I'm sure it will work, but don't forget it and leave it in there too long.
The commerical units have circuitry to limit both the voltage and
the current flow. When the Lead and Copper are used up, there
would be an increase in the voltage necessary to begin decomposing
another metal or the water. The current would dip during this time.
The commercial units sense this, and shut off accordingly.
You could probably hook up a milli-or micro-ammeter to watch the current flow,
and when you saw it dip, then pour out the solution and check your bore,
followed by a cleaning and oiling if its done to your satisfaction.
