Query: Good stuff

Many years ago Vaseline quit making what they called Carbolated Vaseline, which was a great product for small scrapes, chapped lips and crotch rot. Forget that waxy old stuff called Chapstick. Petro-Carbo contains carbolic acid and really works well. This stuff is good and you only need a very small amount. A tin should last a long time. It's well worth the price.
