You betcha, couldn't find specs on flitz, but I did find some PUMA!! /ubbthreads/images/graemlins/smile.gif I've read somewhere that Flitz has a mild abrasive and a chemical tarnish remover, but I didn't find it.
FWIW, I've used JB non-embedding bore compound, JB Bore Brite, USP paste, Flitz, MAAS and Simichrome for bore polishing, or lapping as some call it, on new bores of factory rifles, it seems to reduce the fouling build up and makes cleaning easier, reduces break-in time. For me, it has become SOP, doesn't seem to hurt anything. I've read numerous threads about using JB non-embedding bore compound and it not causing bore damage or unwanted wear, so I continue to use one of the above, they all seem to work for my purposes. I use Varmint Al's method, sans the moly bullets.
