I'm extremely pleased to have heard all the many success stories from people using this simple plating method!
Thanks for all your interest and input!!!
There are four questions that have been asked about the video so often, that I wanted to create this quick web page to answer them in detail for you.

The first is: How thick, and how durable is the coating?
The answer is, that despite the very simple method in the video, I've found the coating to be highly durable.  I've even scrubbed (polished) pieces with abrasive Scotch Brite pads and cleanser with no damage to the finish!
Thickness depends on time, and very thick (almost foil like) plates can be gotten after 30 + minutes.
Builders have written to say the process can be sped up by connecting more batteries in PARALEL, so the voltage stays low, but the amps are higher. 

The next Question is: Can cheaper chemicals like Nickel Sulfate (available in large quantities on eBay) be used?
After some experimentation, I found that the Nickel Sulfate recipe (below) works spectacularly well!
If you are plating larger quantities of objects, you can save quite a few $$ with these less expensive chemicals.

The next question is: Where can I get the nickel plate for the + electrode?
Most industrial supply companies have these, such as McMaster Carr.  But there are cheaper sources such as nickel welding rods, or even Canadian nickels (pre 1982) all of which are available on eBay.

And the last question was:  How can I polish items to a high brightness?
I've been using "Bar Keeps Friend" cleanser, which is available anywhere, and scrubbing pieces with that cleanser and a kitchen scrubbing pad.  This works miraculously well to give a shiny, even, polished finish!
