I saw an advertisement for such a system (brand is CounterAct, few other types exist). Anybody might have used or heard about that? This sends a low amp current and supposely kind of cancel the rust process..... bit sceptical

Leaving on eastern part of Canada, humidity is a bit higher than west coast. Even though my 68 Mustang is stored in a heated garaged, I would not mind something that would add to the protection against humidity effect. They claim it's good also for the effect of salt galvanic corrosion, present on west coast....

I'm wondering if this is just a gadget, with low performance. On these things, before you can evaluate the results, it takes few years, then it's too late to complain, damage is done and warranty of the system expired long time ago.

Prefer to get some REAL feedback by users before doing anything.
