A word of caution, Big H. ALWAYS have the sandpaper wrapped around something flat. DO NOT ever sand with the palm of your hand or your fingertips. That was the toughest thing I had to teach my students when I was teach auto body repair. Without the block in the paper you will wind up with uneven streaks that won't buff out. Take it slow and easy. It's not a real easy job, but the results are worth it.
