Yes, there are quite a few posts in the FAQ about using a buffer with red, green and white rouge.  You may want to start your search there. It is tedious and time consuming, but well worth the effort.

It can be done -

1) Clean all grease and grime away
2) Use oven cleaner to remove old clear coat
3) Wet sand 240, 400, 600, 1000, 2000 until smooth
4) Use 1,700 RPM buffer with red/brown cutting compound
5) Clean part and remove all compound
6) Use white compound and flannel buff wheel to achieve mirror results - NEVER contaminate your white/flannel buff. Use only after cleaning all of the brown off the parts.

Buffing time is less than 2 minutes if you get the right tools and get the parts up to working temperature. The block compounds are made with animal fats that are desined to melt at 140 degrees F. You'll need to wear cotton gloves to hold the parts - that way you can feel when the temps are reached. When it's right, the part won't drag and there will not be any black on the part. If the part is black, it means you don't have enough heat. Trust me, I learned the hard way how to buff parts - This set-up is about $350 with the stand, but I paid for it with just 1 bike and it's mine for as many as I want to do. Tools are always a good investment if you enjoy this hobby.

That's a really nice finish, Gordon.
I just went and had another hard look at some I did a while ago, and you've encouraged me to have another go for even better results......... :)

I've heard that using a sealer like Zoop is the way to go if you don't want to touch it for a year or so to touch it up. Is this correct or not worth it?

i wet sanded some of my parts and then just went over them with "Never Dull" (comes in a silver can). they arent as shinny as the post before me but good enough for a poor boy like me, lol.
if its got tits or wheels then its gonna be a pain in the ass at times.

Which Mothers polish do you use? There is a fair bit of choice on their site and I will need a few gallons for my fuel tank alone.

I used zoopseal after polishing on my cb750 two years ago. The shine still lasts, and I live in a very wet area.

I just use the "mag and wheel polish" on my stuff after all the sanding and buffing.

Green Ape works great for a finish/repolish product but I have only been able to get it from a guy in Chicago we race with. If you run across any get it.
