Interesting stuff. I like the fact that it uses tree resins and bees wax instead of lanolin or animal fats that leave leather greasy and just migrate back to the surface where their of no use.
I've been using Lexol for many years to condition my (and my kid's) baseball gloves, track leathers, etc. because it doesn't 'load up' the leather making it feel heavy or greasy, plus it doesn't migrate. Wonder if this stuff accomplishs the same, will have to try it out.
