I've been buffing a lot of parts on my bike. Between stripping and a fabulous shine is a lot of sanding. (Wet sanding, of course.) When you look closely at the parts you see there are some areas Suzuki didn't bother to put a nice finish on. No amount of buffing will make those areas shine like chrome. So you need to sand them. (You might even need to do some grinding.) And to make sure everything looks the same, you need to sand everything.
Depending on the condition of the part, you might need to start with as coarse as 180 grit then work your way up to 220, 380, 400, 600, 800, 1000 and 2000. Once you get the uniform milky finish,
then you can go to the buffing wheel.
You'll need buffing rouge, also called jeweler's rouge. Google it and you'll find all the sources you need. And you can probably find detailed instructions online, too.
Here are some before/after shots of my buffing. These haven't been on the wheel yet. I just hand rubbed them with some aluminum polish.
