2 identical pieces of steel left unpainted outside in the weather, one with the rust prevention unit hooked onto it and the other without.
2 weeks should be enough to see what the outcome is.

maybe: but from memory the erps system never pretended to stop surface rust. i believe they actually stated that it needed a coating of some sort (either paint or oxidization) to work
from my own personal experience the rust has stopped on my car. that does not prove anything i know, but i was quite happy to try it out as long as it did not promote rust. if it didn't work i had blown less money on it than other items for the car. if it did, i was ahead by miles - both monetary and with peace of mind
i certainly am a satisfied customer - but the car still stays under cover at virtually all times. previously though, staying under cover at virtually all times did not prevent rust
