I don't know if my eyes are playing tricks on me or not, but I have noticed on many occasions that the PC with round out or eliminate linear scratches faster than with a rotary. Has anyone else noticed this ?

really? With my udm on speed 6 and a 6.5inch pad it begins to orbit more than rotate. Ive used 4inch pads and theyve only lasted me about 3 hours worth of use before they disintegrated :mad:

If you were using the same pads and products on 2 scratches of same depth but in different locations on the paint, your eyes are playing tricks on you.

The orbiting is where the real work takes place, the rotating is when you don't have enough pressure on the pads. Just place your hand on the pad and you will notice the difference !
 
The PC may cut faster if you're using 105 and a yellow CCS pad Vs. a white ccs pad with 106ff on the rotary. Even then it'll be a close race to the finish. :nervous2:
 
All those results showed was that it took much longer for the PC to level the paint, and when the PC finally got the paint to a state of perfection, it also caused more damage to the clear.

I agree with Todd's results in that wet sanding is probably the best way to level paint, then rotary, and PC last... the amount of paint removed however had no possible comparisons at all... if he did 2 passes of SIP/orange over a section with the same area both with rotary and PC, then compared paint amount removed it would show the difference... he simply showed that 8-9 passes with PC and the tried pad/polish combos removed more than 3-4 passes with rotary and it's pad/polish combos

Ed, if you haven't already, have a look at this. You may find your answer. :)

Wow, someone already did a nice study on the issue !

I just can't see a PC being superior to a rotary for scratch removal. Are you positive of your results?

I would agree that the rotary has more power in removing defects, but it is the technique that is important, if you use a rotary on a defect without moving it is "all" directions with some velocity then no its not going to remove the defect as fast as a PC, the PC works the spot in all directions even without moving it. So this could be the case I suspect.

David I don't think he meant superior, and even though I don't agree with the results of amount of paint removal, for reasons stated before (same passes aren't made, etc.) I agree with Todd's observation at HOW the PC cuts compared to the rotary, actually making the rotary a more superior tool, not the PC.

If you use a rotary without moving it you shouldn't detail other peoples' cars haha...

For me it all boils down to this. If you have to remove swirls 95%-100% what are you going to reach for to do the job the fastest??



On a hard paint I could do an entire car with a rotary and get it nearly perfect in the amount of time it would take the PC to just do the hood and even then you won't get as good results with the PC for all your efforts.



Now on soft paint it's a different story, the PC will cut well and remove many of the swirls, but most times will leave micro marring as well as not cut out the deeper swirls as the rotary will cut threw all the swirls and in the same time and leave a must better finish behind. Of course both will need to be finished down to remove marring from PC as well as holograms from rotary.



When it comes to removing swirls I reach for the rotary.
