As I understand it, the Pro Honda polishes are very similar to the S100 all cycle cleaner, which is a pretty good product. However, I got this information first hand, and have never tried it. I have seen the results though, and they DO look pretty good....on a bike. On a car, the results may not look as good, because of the large amounts of single colour paints, with no graphics to break it up. In another words, it's easier to be critical. However, you can always try it on a small area and see if you like it.
