Sorry to hear about your chrome problems.
I use to use the same product until I noticed what it was doing... Very fine, but nontheless still scratches.
Now I use a creme product from AUTOSOL called "Metal Polish". It claims to "clean, polish & protect" and I have to tell you that I am thrilled with the product!
Another tip is about the inner fairing on the EG's. I have never used anything but warm water on the inner fairing (naturally I'm talking about the unpainted inner fairings). The inner fairing on my wife's '07 EGUC looks great! Her '97 EGUC looked as good as new when we traded it in on the '07. Some of my buddies have used different products, one that comes to mind is Amoral, and they have virtually destroyed their inner fairings finish when they originally planned to make it shine... NOT a good idea at all to use anything but warm water on unpainted inner fairings.
Good luck!
Mike
