I have some of those wax bars for charging up my buffing wheels for
polishing pen turnings. I've been storing them in zip lock bags inside
a brown paper bag and they seem to be drying out. There about 4 years
old. Still seems like I can charge wheels ok but thinking eventually
these things will petrify and become useless. Any advice on preserving,
reviving or extending the life of these things.. Thanks.. -Jim
