Thank, Iona! I had no idea where to find additive-free aloe vera gel. I have a aloe vera plant on my back porch, but I think the recent cold snaps have done it in It's also such a hassle to try to grind it yourself. You always end up with chunks that won't grind up I may try smearing on the gel, then spritzing it with a little water to make it slicker. Might be awhile until I try this, however, my tail is still in the construction stage.
