As a general comment:
This is why (for the purposes of this list  anyway) that discussions of
process and chemistry should be explicit in describing what is done.

For example:  A "dash" of "#12" solution and a "pinch" of "agent" are
mixed and applied with a "magic gadget".
This does not provide real useful information.

Whereas, "5ml" of a "16% K2PdCl4" solution with ".05ml" of "a .5%
potassium chlorate solution" are mixed and applied with a "1 inch
chissel type sable brush".
Now this is something meaningful that others can replicate.

A well described situation or question will likely get a more
informative and helpful response.  Please keep in mind that not everyone
has read the same books or uses the same personal nomenclature or
technique.
