The bead blast finish on your Kimber is tough, so don't be afraid to start with 100 grit and work your way up to 600 or even higher. I originally took mine to a mirror finish, but later went back and used 150 grit to give it a brushed look. Be sure to use a glass plate and even strokes. If you unscrew your grip screw studs you can do the frame too. The plunger tube is difficult to work arround, but the grips, slide release and safety will cover the areas you have trouble getting to look just right. Be sure to use locktite when you reinstall the grip studs. Use some duck tape on the side of your rear sight just in case you roll the slide a little and touch it against the sand paper. Most of all, take your time.
