Tony,

On vertical application like this with very light etching we have had great success with the 3,000-8,000 grit spinergy pad and the lightest amount of 5x. We make a paste with oxyclean or any detergent and lightly sprinkle the 5x, like your salting your steak, we then polish wet to dry using either grit pad or for very high shine like this we will use both. It's worked well for us.

No need for diamonds in disk form, an etch this light will probably polish out with hogs hair and 5x.

Hope this helps. Take care.
