Also, scratches in SS can be polished out without concern about removing any "finish".
just removing material from the gun.
it's only metal, we can out think it.....
The minute amount of metal that will be removed is of no consequence...just like rubbing out the paint on a car. Remember, SS is through and through, it does not chip or flake, and is highly rust resistant. It depends on what look you are after. I prefer durabilty over flash, so make mine SS.
