I've soaked some rusty parts for about ten days in this CVT fluid, taking them out every few days and hitting them with a wire brush. The results have been disappointing, definitely doesn't work as well as regular ATF for soaking into metal and softening corrosion. I was hoping for some more info on this stuff and what else it might be good for. Guess I'll give the last few quarts to a local trans shop. Thanks guys!
