Well speaking to the creator who I trust, yes. The factors that led to my shoes cracking and such could have nothing to do with reno in reality, but it was a constant for me so I am trying something different.

Glen has, in this thread spoken a lot about the science behind using coconut oil, orange oil and so on. It makes sense to me.
