Check out the link: Defender Plus - Electromagnetic Surface Protection and how it works: (even the paint chip): Defender Plus - How It Works - Electromagnetic Surface Protection Hmmm.....idk about this.... (I know you can use anodes to prevent corrosion but this in a car prob will do nothing..)
somehow i dont know if our primer is zink based. but i could be wrong. it looks like it has to be coated with zink to work or something
galvanized steel used in most cars will provide the zink but just seems bunk to me when talking about a car..on ships yes they work great..on bridges they work great..car eh idk..
