Yes, the link which dkrug posted is the product I was talking about; it is great, but the drawback (for us) is that I couldn't find a way to get it onto a polishing pad/wheel. There is something about the thin cloth which it comes on that makes it an integral part of the process. We later went to the Good Guys car show in Columbus, and found someone else selling Wizards who showed us (and we purchased) a liquid that has similar qualities as those in the metal polish in the small tin can, but it still didn't quite do the same job.
With this product, you would have to do it all by hand, which on an AS, that would be so tedious! I do want to say, tho, that it really is just rub it on (I did it in a circular motion), wipe off and do again and the oxidation is off. I incorrectly called the oxidation corrosion before, and I'd like to correct that now. We were able to get some really nasty, burned into the skin off with this, but that did require more rubbing.
It's a shame there isn't a way to get that cloth to stay onto a polishing wheel, because it would certainly speed up the process.
Oh, I'd also like to say that this is good for areas which are small or hard to get to. I used it on one of our rain guards which had very bad oxidation, and within about ten minutes, it was shining like crazy.
