Do your polishin first with graduatingly finer wet/dry sandpaper. Your finished product will depend on your sanding....use something strong to degrease the parts to be blued....after each coat of blueing, rinse in water, dry, then degrease if you touched any part with your bare hands, then blue again, do this repeatedly til you reach the desired effect. Oh I almost forgot....get the old blue and any rust off with the blue/rust remover! Take pictures, and post them....folks on here love to see that!:up:
