i was wondering has anybody ever used whiting ,talcum power or corn starch to remove the swirl marks or ( light scratches )when finishing your metal, does this method work ? if so how would be the best way to do it ?

it seems like no matter what method i use to polish it almost always comes out with little tiny light scratches in the finish some come out good and some come out bad ,, does anybody have the ultimate solution for this fix ??
