I started by using CaliforniaCustom, a product that has been mentioned here on VAF. It is a product designed for many metals including aluminum. While going over the aircraft I quickly realized this was not going to get to the finish I wanted. In the first image on my original post the area of the wing to the right is after using CaliforniaCustom. To be fair I only went over the area once. Had you looked at the wing up close it looked pretty good but it was a little cloudy and yellowish. Had I made another pass with that product it would have been a better finish.
Then I switched to Nuvite products. A friend of mine has a polished Swift and he loaned me his Cyclo polisher and some Nuvite C and S. He gave me a five minute lesson on the size of area to work on and using the two products. I started with C and a compound polisher and went over the wing, working in small areas (2'x3' maybe.) In some areas I made two passes with Nuvite C. After going over the outboard half of the wing I switched to Nuvite S and the Cyclo polisher. Again, in a couple of areas, I went over it twice with the Cyclo and S. That got me to where I am today.
I believe that I should have gone over many of the areas of the wing with Nuvite F7. Orignally I believed using the CaliforniaCustom had done enough polishing that I could skip the step with F7. In my case that was a mistake. One thing I quickly learned is there are a lot more scratches on the surfaces than I thought; cleco marks around rivets, or marks from the wing rack and shipping marks (QB wings.) The polish will turn black as you work the with the compound polisher and get caught in every depression or scratch. All those scratches really show up and I had decided to polish early on during the build so I tried to be careful. Had I initially used F7 I would have reduce the number of passes I made with C and "healed" many of the scratches. From now on I will be using F7 in many areas.

that is where I purchased the Nuvite products. He also has some interesting information and a video about polishing aluminum.
