The book is called "The Grounds for Lightning Protection"
I'll look further and see if I can find a source. Or you can check on
www.google.com <http://www.google.com/> and do a search for the above.

can't remember the exact title but its something like "The

I tried Polyphaser and they don't sell it direct.
