When you put a zinc on the shaft, there is normally a bit of slack in the whole assembly. This is usually fixed by whacking the zinc with a hammer to seat it on the shaft. Unless you back up the other side of the shaft with something relatively immobile, you stand a chance of bending the shaft. So, you hold a BFH (large hammer) on the back end of the zinc when you whack it. The thinnest part of the zinc is at the bridge between the two halves, so if you liberally coat those surfaces with paint, nail polish, or whatever, the zincs will not vanish and leave you with no protection.
