I am still using a can of JPW that is at least 30 years old, use it on all my guns, and I have used it as a bullet lubricant and also as a case resizing lubricant. People love to shout about how wonderful Renaissance Wax is, but JPW is probably just as good and FAR less expensive. The very first time I used JPW on a gun was back in the late 1990s. I was shooting CAS using an old Winchester 97 pump 12 gauge. Wow, did that thing ever rust easily on a damp or drizzly day. JPW stopped it, would just apply some before I took it to the shoot if it looked like it was going to be a wet day. Oh, and JPW works on furniture too. I just went over an old grandfather clock case with it last week.
