I beg similar tolerance as afforded Ron, and for the same reason: I have shaving creamed my sink (made of same material as many tombstones) probably about 5,000 times now. And there is no observable effect. The mirror argument is a terrible red herring. The properties of mirrors make it MORE likely for adherence, not LESS likely. Porosity has nothing to do with it. The property in question is chromatographic, not penetrance. That is the issue. I don't recommend shaving cream for tombstones that are made of mirrors any more than I recommend shaving cream for tombstones that are made from car paint. Let's try to stick with reality though.
