Well, which is it? It seems that everybody says use the cyclo if you want to be a little more "aggressive". But it is a fixed speed at 3,600 OPM versus the variable speed of the PC which as we all know, will run up to 6,000OPM. My thinking was that you could get more accomplished at 6,000 OPM than at 3,600 so use the PC for tough jobs and use the cyclos for a final polish/buff type application. Any one like to educate me on this? :dunno :huh Also, there is a Orbital made by Rigid that runs up to some insane OPM's like 10 or 12,000. Would that be almost as aggressive as a Rotary? Would you be able to damage paint at that rate? I've got a car I'm doing Saturday and it has some very nasty swirls, which, unfortunately I believe were made by someone using a rotary improperly before I got the car. If the swirls were created by a rotary, will you still be able to lift them out w/o using a rotary? Sorry for the long post, but hope this will give everybody some answers.
