I have a friend who started detailing cars a few months back. He always argues with me about the PC that I use and get great results with. Today he went over the edge with this statement.
"You can`t cut scratches or remove swirls with a PC. You can hide them but not remove them."
I told him I was going to post this here and am going to direct him to this link.
Everyone chime in here.
Do a test spot, and a PrepSol wipe down for him. If he still doesn`t beleive, then he obviously is set in his opinion, and there will be no convincing him otherwise.
Pick out a nicely swirled black car and show him http://1person1million.com/img/149/r...dc/biggrin.gif
`Flame suite on`
I agree with him to a small degree....
I can see both sides of the coin...
1) I can complete a full correction with a PC and 4" pads, removing 99% or more of swirls. It takes quite a bit of time, though.
2) With a rotary, I can complete a full correction in 25-50% of the time and achieve a better finish.
With a 6.5" pad however, a PC is IMO completely useless except to apply waxes or polish extremely, extremely soft paint.
I`m assuming that your friend is more or less an enthusiast detailer, not a Pro? If so, I`d have to say that a Pro(or people that charge a Pro rate for their services), are more or less cheating themselves and potentially their clients if they rely on a DA style machine for correction work?
Most of the argument is really time and pad surface area.
If you have enough time, you can use the PC to do almost anything that the other two general options can do. At least 99%.
If time is a factor at all on a heavily swirled paint job...for gosh sake use something other than a PC!!!

At a meeting of local detailers this past summer, we worked on an older 5 series BMW, black with scratches, swirls and oxidation. We tried 3 different techniques on 2 sections of the car, 1 on the side and the other on the trunk lid. Two guys did a compounding step with Makitas and I did one with a G110 - I got better results using the same product (megs 95 I believe) on PFW. Hey, they agreed, as did the owner of the Beemer. So, I say it depends on the car, the condition, the pads, the products and the technique. But to say that an orbital can`t do as good as a rotary is not true, there are too many varibles to be considered.
A rotary can remove 1500/2000 grits efficiently. Some detailers or
paint correction specialists do work on fresh paint.
I have a Dynabrade RO head attachment for finishing super soft clears.
Rarely used but it is faster/better at times. So, having both is best.

I removed 100% of swirls on a Toyota and an Audi with a PC using 6.5" pads, all I had at that time. To say this combination is useless except for applying waxes is laughable.

It depends on the paint and the condition. You can easily deswirl a WRX, for example, with a PC. You need a rotary for Ceramiclears.
I think my Ford Windstar has ceramiclear (LOL).
