The polishing comes in after the copper plate. After the copper strike, make sure all of the zincate is COMPLETELY covered with copper. Then plate with your bright copper to build enough copper thickness to buff. Rinse and dry, then buff until completely smooth, increasing sandpaper grit until you get smooth enough to polish. Sometimes, depending on how rough the part is, I have had to copper plate, buff, copper plate, buff, copper plate, buff, polish. Make sure that before you return the part to any plating bath after polishing, that you clean the part well to make sure you have removed all dirt and buffing compounds, then acid dip to reactivate, rinse then plate.
