HeadBanger - DO NOT WASTE YOUR MONEY ON IT!
My old friend is a retired NRC scientist who worked on this technology for anti-corrosion in ships. He told me it works on ships and bridges immersed in a salt-water environment, but salt-water splashed on a car does not allow it to create the proper current to negate the electrical process of salt and ferrous metals.
You are better off with Krown or some other applied rust-protection. My FRS will never see snow/salt while I own it so I did nothing to it for extra rust protection. My 92 Camry, 05 Corolla and now 13 Yaris have all had dealer applied (3rd party actually apply it) corrosion protection. The Camry only had rust on the driver's side rear door and that was my fault for not cleaning out the drain holes in the bottom of the door. No other rust and it was 13 yrs old, saw every winter and had 320,000km on it when I sold it. The Corolla was totaled in 12 but it had zero rust showing anywhere.
I just can't stand the mess all of these applied coatings/treatments leave behind - either the drippy stuff on the lane-ways or the sticky stuff coating everything under the hood
No way was I doing it to my FR-S!
I told off my dealer for trying to foist that snake-oil electronic rust protection crap on me and their other unsuspecting customers. $500 cash grab and they know it is bunko
Spend that $500 on a OFT or suspension upgrades or something useful instead
