I buy the chemical from here in Oz http://www.janekits.com.au/mainframe.php
The process couldn't be simpler, I clean, acid wash the parts in dilute sulphuric acid, wash in detergent till I get a complete water sheet on the surface (no grease) then hang then in the solution.
There is an ideal temp but I found if I simply keep it at the temp where water vapour just comes off the surface, thats about right.
Simmer for between 40 and 100 minutes depending on how thick you want the plating.
As there are no electrodes, the plating is completely uniform even inside hollow parts.
It's the best thing I've found in years & has been a godsend for the Daytona progect.
It's clear white when polished, no yellow at all. Looks like chrome.
The processs is used in major industry these days and the plating can be hardened significantly (they commonly use it for hydraulic rams)
I was lucky enough to obtain a pdf document with some very interesting data which I have attached here.
