A little disappointing on the quality of the polishing job. The other three are okay, just this one is a sad job.
I broke out a sanding drum on a drill motor with 180 grit emery paper to start cleaning up the file cuts on the new openings.

after a few minutes of work this is how they turned out.

I ran the drum on the openings going from the 180 to 400 then 600, 1000 and finished up with 1200. Smoothed the edges good enough that some heavy polishing will bring the shine back.

Once I had that done I got busy taking out the scratches and gouges. I started with 400 grit on a rubber Dura-Block and started feathering them out.

Once I started sanding I ended up going over the whole face of the wheel. There were so many heavy cut lines and deep grooves from the half-assed factory polishing this was the only way to get a smooth surface... You can see the waves in the pic to the right of where I started sanding.

here is another pic after I had most of the scratches and gouge worked out. This also shows the waves better.

I used WD40 as a lube to "wet sand" all of the waviness out. I spent about an hour and a half doing this. Cleaning and re-sanding until all of the low spots were gone.

The hard part was getting the surface flat again. Once that was done it only took a couple of hours to step up through the grits. Going to 600, 1000, 1200 and then 1500. You can see the shine is already starting to develop at 1500.

I stopped a O'Rielly's tonight on my way home and picked up one pack each of 2000 and 3000 grit. I'll work at getting this ready for final polishing this week.
I ordered a nice polishing kit from Eastwood so I'll get all of the rims sanded out to 3000 grit before I use that.
The wheel looks a ton better with all of the openings repaired!

These will be beautiful once they are polished correctly.
