may 22, 2008 Hi again joshua. still cant give a plating cost estimate, but can probably help you a little bit with the problem of "dont understand most of it". On the first item, "electroless nickel" means electroless nickel plating; this is an autocatalytic plating process (the reducing agent is in the solution, rather than requiring electricity to reduce the nickel ions to nickel atoms.
