Hi Paul,
I would like to hear answers to this question as well. Now that you mention it the only product I have ever used or that I can remember being discussed is the Novus line of polishing products compounds.
Here on the forum folks unless folks are subscribed to this subject area they won't get your question until they just happen to visit the page. Many people register on the website but don't go ahead and subscribe to their areas of interest. You are are likely to get a lot more responses much more quickly if you post the question on the listserv.
Best,
Ashley
