I'd begin with wondering about the stainless steel surface. What kind
of stainless steel do you have? Do you want its surface clean,
etched, oxidized, anodized, phosphatized, etc. as primers? "Clean" or
primed, do you want it further activated for adhesion with reactive
silane or titanate surface modifiersbefore teh final deposition?

This is good stuff! If you can show a process or composition of
matter not obvious to one skilled in the art, with component parts
that non-linearly add (synergism!) to a desirable sum, you have a
patentable invention. Since it is now exposed in the public domain
you had better get cracking in reducing it to practice and then
filing.
