How to Coat Plastic Spheres with Zinc?

I am looking to coat a glass or plastic sphere that is 1mm in diameter with zinc. The sphere can be conductive if required. It can also use a undercoating of a metal if required, however must be thin (Inert to KOH) . The film thickness of the zinc is 100 microns. Is this possible?

We have plated 1 mm spheres made of White Metal - some concoction of aluminum-zinc together, you need special equipment, but yes it is possible.

Zinc is a poor choice as it will dissolve in either acidic OR alkaline solutions. It is quite good for the mid pH ranges or short durations.
