Ive completely left them alone for about 2 1/2 months. And I have seen VERY small progress, if any. I think we all kind of trick ourselves into seeing more progress than we actually get. The only progress Ive really seen is a very slight thinning of the crust. If I had to say though, this method isnt really working. Theres no way this is just a simple wound, and the "leave it alone method" treats it just as that.
