Kinda sounds like one of those Miracle Inventions you see advertised late night on infomercials. .... seems a bit sketchy to me. Personally, I think if you want your car to not rust, swap all metal parts with fiberglass
Its called cathodic protection, I couldnt think of the term before; and I know that it does indeed work. But something has to oxidize...and if its connected to the battery the internals of the battery will. Which = ($$). I am also concerned with how far the protection will reach. The furthur from the source the less protection...so the trunk may be vulnerable. Any comments?
Its kind of funny you started this topic because I manage the reconditioning department at out ford dealership and theeee best paint protector is duponts teflon coat (R-2000) they put a 10 year gaurentee on the bottle that says you will not see so much a one spec of rust on the vehicle. Also the teflon coat prevents oxidation up to 10 times as long as the clear coat. This stuff kicks a**.
