You want a gun oil that says it prevent rust... not one that says inhibits rust.

You want a gun oil that says it either removes, eliminates, relieves, pushes out, sweeps away, absorbs, drives out moisture/water... etc.... plus may have the wording "water soluble" as describing the oil.

Note... I am talking about "inside the bore". Bore Butter can be used outside the bore/exterior metalswith good success.

I'm done here!
See Ya' on the next thread trail.
