First off there is a ton of information on methods in other threads. Take the time to read them to get a better understanding of what to do. Watch the videos on your tube as well. First off you need to strip the clear coat if it has not been done already. The condition of the skin will determine how aggressive you need to be.
For the Bright Work Polish I started with a wool pad on a DeWalt angle grinder. the polish is spread out over a small area similar to applying wax on a car. Then use the wool pad to clean polish off moving slowly across the area in both directions. The 2nd step is identical to the first only a less aggressive polish. For the 3rd step, I used the Cyclo polisher with the flannel pads from Perfect Polish. Between each step it is important to clean off the remaining residue. I use the Mineral Odorless Spirits from Home Depot and use micro fiber towels to wipe off. I use a 2 step method. Use a spray bottle to apply the Mineral Spirits. First wipe to get the bulk off and then use a clean one for final wipe. I use the environmentally friendly version of Mineral Spirits as it seems to be easier to use for me.
If there are still cloudy areas, it means there is still corrosion on the surface. I tested a small area last week by sanding with 1500
grit and then followed with 2000 grit. It made a real difference in the shine. Depending on the condition of your skin, you might even have to use a more aggressive grit to start with. There are other threads that talk about sanding as well but be careful not to sand through the finish layer of aluminum.
