I really would recommend sticking with polishing by hand
Just try it & see--nobody can predict the results. Never used this product, but suspect it's not much more abrasive than toothpaste--may not help, but should do no harm. Thing is, if results aren't satisfactory (and I kinda suspect they won't be), you can always take it to the "next level" of abrasiveness, but you can NOT go backwards to undo damage caused by too aggressive an initial approach.Some have recommended mothers mag and aluminum...
Simply because I suspect--but don't know--that the abrasive may be too mild. Which is why I said "nobody can predict results" without testing it out. A report on its effectiveness (or lack thereof) would be of value to all.Why is it that you expect unsatisfactory results?
Flitz, and a microfiber cloth. Since it's probably not locally available Mother's is a good substitute. As gearchecker says, it's not like you can put material back on.absolutely. Do you have a preference in polishes on your own pieces? Or a preference on nickel plate in similar condition to this?
Most commercial .44 Spl. is loaded to very conservative pressure levels because of all the "old guns" still in circulation. An exception might be some of the specialty ammo makers like Corbon & Glazer that load high-pressure rounds for modern guns, but those are labeled to that effect.The only rounds I can find anywhere near me are Hornady 165grain ballistic tips. Will the 165g be ok?
