Nothing will prevent rust entirely but IMHO this helps slow it down.
I go to Fraser every year at least once but usually 2 or 3 times and the only rust I had was above windscreen after a dodgy installation of replacement windscreen.
Nothing replaces thorough cleaning after beach trips with several washes and sprinkler under vehicle also several times.
I installed a system with 8 pads, time consuming running the cables etc, however found the unit induced a 'field effect' to the vehicle and basically killed the ability to operate my HF radio - needed to wait up to 4 hours for the interference to decay to zero before I could use the rado. As comms was more important to me than corrosion protection, I ripped it off. I also think it a help if correctly installed however this was an undocumented and known issue when I delved into the issue why the HF radio wasn't receiving or transmtting.
