It appears to be in good shape and not drying out any although it does have somewhat of an ugly gray color to it not that it matters. Any of you folks ever used it and if so, lets hear your opinions....BPS

I still have a tube of that in my old MZ box. It worked, don't remember anything bad about it.

I used that many years ago. It worked fine. But for some reason we got into using bore butter at the same time and that kind of went by the side.

I used it back in the 70s, then went to SnoSeal believe it or not...

It's bees wax, castor oil and a touch of Murphy's Oil Soap...
