Hi Cracktower, The grit is not listed as it is a very smooth compound. You apply the one for the materiel you have to the buffing wheel and then use the buffing wheel to clean the metal. Thanks for asking. Greg
Hi Ptm77, This is for hard metal as it intended use. I cannot say it will work with other materials. Thanks for your interest. Greg
Hi Scuzzer, This is the hard metal cleaning compound, What you need is the soft metal cleaning compound A04SM21. Thanks for your interest. Greg
Hi Duchess. This can be used to polish a metal mailbox. Thanks for the question.
Hi, bub. This unit is for hard metals only. It should not be used for soft metals like aluminum.
Yes, the product works great to put a mirror finish on axes and/or knives. It can also be used to sharpen them.
There is a specific compound for polishing marble, look it up on google
