Ottawa, lard or not, he should go with neatsfoot oil - the Pure Neatsfoot oil, not Neatsfoot oil compound. Years ago I had problems with mink oil and have not used it since. Like neatsfoot oil compound, all of the various Pecards leather treatments and many other modern leather treatment compounds, mink oil has petroleum products included and is just not good for leather in my opinion. Pure neatsfoot oil does not contain petroleum products. Maybe Chuck will post on this with his advice, he knows far more than I do.
