Sounds good. What did you put in there as an exfoliant and what was your SF? Mechanic's soap (and gardener's soap) need an exfoliant in them to do any good at getting the dirt, grease and grit out of the cracks and grooves of the skin. By itself, I think it would make a wonderful soap, but not for a "dirty job" like that, because it is so conditioning. However, throw some scratchy stuff in there and that would be heaven on earth for me. I think it would make a good shower bar for dry winter skin if it had oatmeal flour in it as an exfoliant. You can easily make that by putting some oats in a coffee grinder and pulverizing them to powder.
