A guy who sells them online has been emailing me today. He was quite emphatic about the use of softer buffing disks and letting the buffer do the work, not the user. I bet those folks with burned off paint put far too much elbow grease into the use of the buffer and didn't do the job slowly and with a light touch.
I bet a cautious user like yourself would do fine with it. Check out this page I found on how to use it step by step with pictures:

I tell you what. I'll try mine out as a total nooby without anyone showing me what to do and post the results good or bad, with pictures, even if it's embarassing... but I'll start on my wife's old Honda and not my Boxster. I'm no idiot!
