Hey guys I'm looking into this electronic rust guard protection and am curious if it actually works. This is for my daily driver. I have been looking at this one http://www.ebay.com.au/itm/Electronic-Rust-Protection-Corrosion-Guard-12-points-/150678828419?pt=AU_Car_Parts_Accessories&hash=item2315287583 for example. Has anyone got any feedback or know of any good quality systems available?
