This is BS ,there are systems like this that the armed services use, but the voltage needed to produce any results that would keep a truck from rusting ( like 440 volts and 55 amps) could never be produced from a truck alternator and battery system. My brother -in -law paid 450$ for a similar system for his 06 Tundra ,when it was new. He has nice green and red lights that blink on and off, but it has yet to prevent any rust. He never had any other form of rust proofing done because he believed that this BS system would keep his truck rust free. Well guess what, the truck has been thru 2 exhaust system , shocks and numerous other parts destroyed by rust. He now believes that this may have had negative affects on his truck causing accelerated rusting. I have a '95 obs that I run WVO in a separate tank , anybody that has used WVO knows that its awfully hard to keep the oil from spilling all over the bed. The frame that the oil drips onto is like new condition, even after going through numerous Western New York winters coating the frame in salt to the point that its white. So don't waste your money on these BS systems. you will loose , the company will get rich and the rust will win. Just my 2 cents
