The process is like this: You want the chrome part to be the sacrificial + lead while the iron rod is going to the be - lead. I did a wrench just goofing around and the darn thing came out stripped. The same way they plate metal in a chromium solution, the chromium is taken out of the liquid and is attracted to the plating piece. Your bumper will become the chrome source to plate the rebar conductors. Its opposite how they derust stuff. please try with a scrap part before you find the process pits your bumper. The amount of time is what dictates how much the stuff comes off.
