I know many people frown on it nowadays, but I have found it very useful for wet conditions - the thin spray on stuff, and I still use the thivck tinnrd dtuff on abcesses once they get past the raining stage.
I haven't used it in years, as there are more modern products that seem to work better. But the smell! Add that to the smell of glycerin saddle soap, and proper English leather and it takes me back to being a little, pony-mad girl at the riding school.
