I had a wicked set of black rings left on a honed carrera top from my Woods Lifter..Nothing and i mean nothing would remove it..Tried every poltice known and nothing..Finally I broke into the silver can and wetted my finger with some powder....BAM!!!! no stain.

I now need to know where I can buy this stuff and what grits can I get it in...CAMERON DEMILL you are my hero!!!
