Two more attempts...
The second polishing is virtually flawless to the eye. Even the previous pic looked extremely good.
Things I must keep in mind, aluminum is one of the most reflective metals, I am exaggerating the ever so slight imperfection with a bright led light , the image on my monitor is about 10X and perfection is not an option.
So, I'm done polishing. From now to anodizing it will only a touch well worn soft cotton. A paper towel will scratch the finish, ask me how I know...
I achieved this level starting with the piece in the previous post.
Wet sanded with 1000 grit then wet sanded with 3000 grit (ran out of 1500).
Took an old soft T-shirt and laid out a 10 X 10 piece on a counter top. Added a liberal amount of Turtle Wax rubbing compound to the T-shirt piece locking it down to the countertop and proceeded to polish one side then the other.
Then on to a freshly cleaned and "loaded" cotton polishing wheel. Whew!
