Rhodium of Antiqued Silver

We are treating a number of silver pieces with Liver of Sulphur to
promote the “antiqued” look, but we would like the polished areas
rhodiumed to retard tarnishing.

Does anyone have a technique to do this? When we electro-cleaned the
antiqued silver and then rhodiumed it turned brownish and appeared
to be very easy to remove.
