Thought I would complete the documentation of the experiment,as I have now figured this out (I believe).
From the previous pictures, I took it to 1000 grit wet/dry sandpaper. I then received my sanding pads from Micro-Surface, and continued going progressively finer. I went from Micro-Mesh 3600 to 12000 (don't get excited, 3600 is the equivalent of 1350 grit, and 12000 is somewhere around 3000 grit). I didn't take any pictures, because the differences would not have been visible in digital pictures.
I will go through the last part of my process, completed this afternoon after work:
Wheel looked like this, sanded out to Micromesh 12000, sprayed with Flitz Aluminum Pre Clean:
After polishing out with Flitz Metal Polish and their Large Buff Ball (Power Ball equivalent, but made of strips of Microfiber felt vs. foam):
That is a little bit harder to see because the background is different, so using the same background as the previous pictures:
Some close ups:
(edited to add the final picture to show the level of clarity/gloss; reflection of my hand)
To document this from end to end:
1. Abrasive blast with 60/30 crushed glass. This also removed the machining marks.
2. Sand with Wet/Dry sandpaper starting at 400 grit to 1000 grit.
3. Using Micromesh, continue to sand from #3600 to #12000.*
4. Spray on Flitz Aluminum Pre-Clean and wash off with water. Dry off any water.
5. Using the Flitz Metal Polish, go over all surfaces that are bare metal. Final wipe off of any polish residues.
*I am not sure the Micro-Mesh pads are the best way to go. It may be better to go with the Micro-Mesh sheets. Probably better value for the money.
I am also not sure if the Micro-Mesh step is even necessary. I may try going straight from the 1000 grit sandpaper to the Flitz polish.
I don't know if the Flitz polish stuff is the best stuff out there or not. I'm not saying that it is, its just the stuff that I had. I'm sure that a lot of other products on the market would do a good job, possibly even better than the the Flitz stuff. I'm just happy with the results that I got.
