hey all, i recently purchased a graflex clamp from Jeff Parks (I know, I know, but no one else was selling a clamp at the time :cry) but sadly the nickel plating is a liittle thin and there is a more than slight brass tinge to the thing. That being said, could i use rub and buff on the clamp to better match the color of an original graflex clamp? Ive never used this stuff before, so any and all tips/tricks/advice is greatly appreciated.
