Trust me, the paint helps, but it only goes so far. even if i maintain the finish, weather will take it's toll on the car, it's happened with every car I've owned. Don't know how bad new orleans winters are, but here in the chicago area, it can get brutal.
These things work, I have a couple friends that bought them and they swear by them. Also, once you buy them, you can just install it in every car you own down the road; it's a one-time investment.
The protectant that comes with the kit is simply a conductive polymer, they recomend you apply it once a year, but honestly, it shouldn't be required for the system to work.
Many may wonder why all cars dont rust out, since the electrical system is grounded to the chassis, that's because it's a negative ground(-), and you need a positive charge (+) for rust prevention to happen. the current the anode puts out is mild, about the equivalent of a 9-volt battery, but it's just enough to do the trick.
Don't believe it works? here's an experiment for you to prove it does.
take two cups of water, and ad about three tablespoons of salt to each cup. mix them up good.
in one cup, take a nail, and put it in the solution.
in another cup, do the same, but first. take a 9-volt battery & battery clip, and hook it up to the nail like this:
9-volt Negative (-)----<==Nail==|----9-volt Positive (+)
where "==" is where you wrap the wire around the nail.
Now, you have current running through the nail, simply put the nail into the other cup (keep the battery out of the cup.
Let it sit there for about a week or so, afterwards, pull the nails and examine them. the one without the battery will be rusted, the other nail will have a lot less rust on it (or no rust at all.
Trust me, this stuff works. It's been done for years, but most people are skeptical because of the pricetag and the fact that most people have never heard about it. BTW, if done properly, it will not damage your electrical system at all, and even works when the car is shut off.
Example: Cars electrical system is powered off an alternator when running. current flows through sheet metal in pulses
<-< <-< <-<
What this system does is it sends a mild positive(+) current between
the negative(-) pulses coming through the alternator, So it'd be more like this:
<-< >+> <-< >+> <-< >+>
the negative pulses are moving toward the main negative power connection, to the car's battery. but the modules sense this, and send the mild current from one annode to the other, Which is why the kit has 2 boxes to be installed (one positive annode, one negative annode, just like the "nail experiment". It's sort of like a low-power, secondary electrical system. The + current is so mild, any residual charge just "Goes with the flow" on the next alternator pulse, and the electrons ride the wave back to the battery. The only possible drawback to this system would be radio noise interference, which isn't a problem for me, since I listen to CD's in my car anyway.
I'm gonna buy it & try it. Besides, paint doesn't cover every
part of the metal on a car.
