"Not quite right, polish is not polish,..."
There are few sources for the red rouge (ground rust) or white rouge (diatamaceous earth) used for polish. But, the effects of both are virtually the same on brass cases.
I have used pure polish, bought in $4 red and white rouge cakes from Lowe's, to polish brass by scrapping a small amount off with a sharp knife blade into new cob media. Each type worked as well as anything else sold for tumbling. So, polish is polish. Now, the various carriers of many comerical polishes (light oils, water or miniral spirts), plus some addititives (such as ammonia, liquid waxes or "polymers") make some of the commercial concoctions more or less suitable for our use but that doesn't change the polish.
NuFinish auto polish is inexpensive because it has few such additives. That makes it near ideal for reloaders.
It's really doubtful that polished brass, with or without automotive liquid wax additives, will "reduce" wear on a case hardened steel die and certainly not for carbide dies. But, that myth sounds so good seems it just has to be true; NOT!
