electronic rust protection???

[bradcad]

I dont really know for sure but I bought one after seeing a bloke driving a rodeo ute steel tray, tray and sunraysias were typically chipped and grazed, yet no rust. I fitted one (different brand to the ute) to my Vitara, only had it for a year but she lived on the beach, and i could not see any evidence of rust in a then 8 year old car...bull bar, tow bar & scrub bars just didnt show rust..

and it cant have been the type of paint on the rodeo, because at the time I was a detailer at a 4x4 yard, and the same type of rodeos had to have the trays polished once a fortnight to remove the rust stain dribbling down from the steel latches.....so i was kinda convinced
