Just thought I'd share my findings now that I have some experience...starting using the Auto Int. Decontamination system a couple months ago in an attempt to tackle the severe rust contanimation problem we have here due to the salt air, industrial fallout, the nearby airport and a variety of other factors. I have found that it works "pretty" well, but if the rust is bad...it will only scratch the surface of the rust particles. However, used as a monthly prevention wash...it seems to be working well so far on a couple test vehicles that have always been prone so severe rust. I can see where this system would be a big benefit on thin, soft, black paint (like a black honda) where you would otherwise have to clay the rust out (and then polish because clayinig rust out almost always marrs soft paint) a few times a year in this area...possibly one would be able to use the decontamination wash 4 or 5 times per year instead - the advantage being you wouldn't have to polish after claying...saving paint.
