I am getting a Lone Wolf Compensator and have found out it is made of mild steel. I originally wanted to give it a mirror finish to it with some mothers mag polish like I have done to the LW barrel. However, the barrel is stainless steel and the compensator is mild steel. I heard mild steel can be polished but will rust very easy. Does it really only rust in outside conditions? This is only a range gun. How can one prevent rust once polished? Or is this not the route to do
Also, if it is recommended to not polish, I would want to black it out. What is the cheapest/most effective way to go about doing that given the material?
Here is the compensator
