I'm not sure whether you carry all the necessary stuff to make up some of
Mike Ware's formulae from scratch (the chemistry is on his web site), but I
would have thought it might be a good idea, in case anyone wants to have a
go. Of course I could just be asking you to waste your money - I'm not sure
how hard any of this stuff is to get in the USA! But his stuff is (as you
know, no doubt) very well researched and worth investigating.
