Cool-Amp 
#1233-500
Cool-Amp was originally developed to protect copper/brass and bronze against
corrosion and maintain a high conductive surface. Copper and copper alloys
corrode into a non-conductive surface oxide.

<Simply clean the contact and apply Cool-Amp with a clean, damp cloth. It
applies permanently, depositing a coat of pure silver that cannot peel off
and will provide lasting protection against oxidation and surpassing
electroplating and performance.>

cool stuff ;-)

Guess it will be pricey.
Must check if it contains any really nasty chemicals.


Oh by the way - if you put a piece of iron or steel into CuCl etchant it  
gets plated with copper - how come?
