We all like different things and customizing guns makes them unique. If the stainless steel is scratched up you can have it bead blasted back to a nice matte finish, much like it came from the factory. You can also have it coated, two-toned, etc. I have seen 3rd gens with a gunmetal grey cerakote that looked awesome and once I saw an originally blued 6904 coated in NP3 that looked nicer than factory new 6906. I really like NP3 and Black-T and it wears better than most. Most modern guns have a coating or finish on top of stainless, like the entire M&P line. So whatever you want to do will work. Look at burnt bronze and copper cerakote, both seem to be the rage right now.
