Yep, this works! I've even gotten to the point that I'm working a hard rubber over a cowhorn tip for a rubber/cowhorn lip stop. This polishes out very nicely. If this (Austy's tips) will work on cowhorn, which is very hard, it certainly will work on cork and other material!
However, my wife is disappointed. She thought this meant that she could drink mo' wine so I would have mo' corks. But I've notices this hasn't slowed her down much.
Thanks Austy. Great help.
