Apart from Adam, how seems to understand A LOT about chemistry, I'm not
aware of anybody who has developped his/her own chemistry which he could
SUCESSFULLY use. Alas, don't loose time on this part except chemistry is
sort of your hobby.
I simply BUY the chemistry. It's not that expensive in the long run. You
must buy some stuff in certain minimum quantities (which varies from
supplier to supplier) but in the end you have a professional product,
leading to repeatable reliable quality results.
I'm often amused when reading certain forums where people got to lenghty
excursions to get metallisation to work. If they would only spend a
tenth of the time and money on the right chemistry they would be up to
speed in a snap....
The easiest way IMHO is to get in touch with a boardhouse. You may have
to visit them and talk to the people there to get to results, and if it
even were for watching how they do it (which gives a lot of
information). Usually these people are more than happy to help out with
small quantities for hobbyist use (if they realize that there is no
competition ariseing out of this).
Just my 2ยข of course.
