Actually some of the posts further down in that forum had some decent info I think.
However I was just being a wise a$$ and posted the first thing that popped up from a ggggoooogle search

I have used a product from Germany on the chrome of a 63 Avanti that really impressed me, but unfortunately it's in the glove-box of the car and its under 3 layers of plastic and two car covers all tied up to keep the wind from blowing them off
As I recall it still required additional elbow grease which I had to supply
So of course I had to next look at what you posted and I think the Simichrome might actually be the stuff I used (it's been over a year now) It really was good sh!t!
