With the 300mm dome now in position, it was time to decide on what to do with the finish.
Out of the box, I thought it looked fine....it didn't have heavy spin lines like my other dome has. If anything, with just some light polishing, it should look fine.
The left side is how it looked out of the box, the right side, polished.
Here's how it looks after simply using Mother's Aluminum Polish and the polishing pad from my mouse sander. Perfect!
