Your choice, but I have replicated a BSA 70's lacquer finish using careful application of spray-can Hammerite (with plenty of cutting back) and a seasoned collector friend couldn't tell the difference. Obviously, this is if the gun was originally lacquered, not blued!
Like I said, mirror finish, tougher than the original. Still, each to their own...
