Sorry :shake: The BreakFree will not stop the browning process unless you rub the bejesus out of it for a week, etc. and them maybe it will stop. But just applying it will not stop the rust, as I have steel wooled barrels to smooth them (card them) then Liberally coat them with BreakFree & the next day they are just as rough & rusted as if I never touched them..
You have to neutralize the rusting first. Ammonia, Rusty Duck, or baking soda/water will stop it but on all 3 you have to reoil & rub the heck out of them or they will start rusting again. The Rusty Duck aerosol will actually remove the rust & leave a black/blue finish, but it will rust again if you don't rub it down good for the next 2-3 days.
You have to get the metal neutralized & the pores sealed off from all moisture & air, then it will stop rusting. If you get air in the pores of the metal, it has humidity in it & it will start rusting again if not sealed off & a rust inhibitor applied. But first you have to stop the rust, that is the starting point.
