electropolishing is not necessary and does nothing to protect the stainless. mirrior mechanical polishing is the best. any type of polishing, be it mechanical or electropolishing will expose the free iron on the surface and it will rust if exposed to moisture. in addition to the electropolishing process most all parts are passivated and allowed to air dry before returned to the customer. it is the Passivation of the stainless that removes the free iron from the surface and should be done to all stainless parts. Passavation can be done to your parts by soaking in cirtus or nitric acid. soaking in Spotless Stainless will passivate the parts just as well.
