I think Khatfull's way is great and is a good source for many people here to learn how to polish without having a garage full of tools to do the job. I own a dual wheel buffer and know how to use it along with tons of other tools that can make polishing a certain part easier, but when I do a bike part I don't mind sitting down with my Mothers polish cranking up my stereo and going to town on it. I use my buffing wheels for large items though like a side case for a motorcycle or stainless covers. I have done bike parts with it also but I do get better results doing it by hand most of the time and I think it is partly because I am working up close and looking for any defect that would need to be worked out while I have it in my hand.
