Hi,

Don't bother with sacrificial anodes on your car. They won't work.

Sacrificial or impressed current anodes require an electrolyte (eg seawater, soil as for ships and pipelines respectively) that surround the structure to be protected. The current produced by the anode travels through the electrolyte to the metal to be protected. Anodes on cars can't work because they are surrounded by air which is non-conductive. You may get a limited amount of protection immediately adjacent to the anodes on a car if there is a thin film of conductive dirt around the anode. Otherwise, try something else like a high quality coating for your car.
