<html> In the shop we rub them out first with 600 grit wet and dry, then with custom made felt belts and the Ivory polishing compound, on the belt sander, our local 3M supplier makes up the belts for us.  Expensive belts, but Oh such pretty results.  The Fastastic is more of a quick field clean up, or get the grease off before starting the full meal deal polishing. As for moisture around the Ivories, the Fantastic is applied to the cloth and is only in contact for a few seconds.
