trumpers- coral skin food as pre-shave

hi every one,
a lot of people on the forums use coral skin food as a post shave but i want to know if any one has used it as a pre shave prep and how it has worked.

I haven't used it as such however they say you can and I have seen reports from those who have used it as a pre-shave. Some like it and some don't, like everything else. Try it and see what you think.
