NP! I read it somewhere but I can't remember. It is a great tip cause it makes them a little shiny also. cleans them up nice. Question for you Stella ... I don't know if it was the base i was using but my clear soap I had to wrap right away or i got sweat bumps like with in 2 or 2 days. And NOT just a few like the whole soap would be covered. Now i did this in the summer so it might be better now where it is not as humid here now, I live in the north east, But I've never waited the 3 weeks. I guess I am due to tinker with M&P again. I sell my CP cause I have been doing that for years and have my recipe down. I've only started tinkering and testing in M&P the last say 6 to 8 months.
