Re: What's the best buffer?
I have the porter cable and although its not bad I just can't stand the vibrations! It does the job but it's very time consuming IMO.
If you are willing to buy a PTG (paint thickness gauge) and a scrap panel to practice on, I'd recommend the Makita 9227C that Greg mentioned.
I used one of these on a rotary training course I done and it was a very nice (but heavy) machine. Correction work is naturally much faster, there are no vibrations and you can achieve a better finish. Although if you aren't careful you can remove too much paint with it quickly and also instill holograms/buffer marks if you don't break the polish down completely.
For a beginner I'd recommend the Porter Cable, but if you can see yourself doing more than just your own car and are willing to practice the rotary would get my vote!
