Review on 🔒 Premium Chromed Forged Steel Class V Extended Receiver Lock - Trimax T5 (5/8", 3 1/2" Span) by Eddie Fowler

The receiver lock fits and protects my expensive BW chrome hitch, but is the hitch bolt locking tab already rusting where it makes contact with the receiver (in just a few weeks of use)? Is my hitch ball all chrome plated with no signs of rust? I was hoping to have a nice chrome pin lock on the receiver that wouldn't rust.
