Why are Rotary's so Dangerous?

Simple question. I understand that the rotary only spins in a circle and if left in the same spot it will burn the paint. So other than that what makes it so much more difficult to use?
I am thinking about getting on just to use as a swirl mark and scratch remover. Then use the pc to polish and seal.

Are the cheap ones ok? Like at autozone or walmart.
 
i think not only the fact of burning the paint, but the fact that it moves soo quickly makes the machine harder to control, and when not balanced correctly it can swirl the paint.

What he said. A rotary is definately not for the novice detailer.
 
It constantly pulls in various, especially if you are just starting out. A RO will stay in place easily with 1 finger holding it. (in theory)
 
From someone that has had a less than good experience with a rotary.

I don't consider the rotary really dangerous, just more efficent and needing some skill to make good use of that capability.
A rotary will remove more defects, (and paint with them), in 30 seconds than a PC will in 10 minutes. That is a two edged sword. If 30 seconds was enough, 35 seconds may be enough to damage what you had already accomplished.

My one experience with a rotary was on very bad single stage paint. Actually, I was able to get it looking great where I didn't go through to the primer.
It was a very short step between shiny paint and no paint.
That wasn't the fault of the rotary, it was operator problem.
A friend of mine with rotary skills used the same machine, pad, and compound on the same vehicle and had no problem.

In the right hands, the rotary is an amazing tool. I honestly believe that the guy that finished my messed up job could actually move the paint from one area to another with the rotary. He says he can't do it with todays paints, though.

I used my DeWalt for the first time about a month ago. I was absolutely amazed by the results when I was done. However, in some areas in the right light, I did make some very light holograms that were a direct result of the rotary. It did, however, remove all of the spider webbing and was like an eraser for some very minor scratches. The holograms were later removed with a finishing pad and some ssr 1.

I would reccomend getting some practice first with a DA polisher. Then, when you feel you're ready, step up to a rotary but first practice on a junkyard hood or your best friends car! :)

Like Charles said, it could be your best friend or your worst enemy!
