The "Ranom Orbital" is the key - with that function, you cannot burn the paint, even on vehicles edges. Body shops use what is called a straight wheel, which spins very quickly and can remove more blemishes used by a trained person. A wheel in the hands of a rookie could be disasterous.
On the Porter Cable, just make sure your deal includes the DA backing plate, sometimes buying this separately is more costly than buying the kit like Griots offers. I like the 8" pads. Here's some info I compiled a few years ago. Don't buy the gallon of wax from Meguiars, it is WAY too much for the average joe and I wasted about half the gallon when it separated.
From an old post:I have the Meguiar's (Porter-Cable) random-orbital polisher, model #7335. The unit works great and I have used it extensively over the past 18 months. This model is designed to use the Meguiar’s Soft-Buff pads that attach to a backing plate with Velcro. A different pad is used for each specific product. The pad numbers and application are listed below. Several vendors sell the pads and buffer, but after trying several vendors (Imparts, Showtime) I finally learned to order directly from Meguiars at (800) 347-5700. I was most impressed with the buffer after it removed the scratch marks of a Springer-spaniel from my driver’s door. My guess is that I saved a good part of the buffers cost in this job versus taking in to a detail/body shop.
W65-DA 8" Dual Action Backing Plate - This will allow you to use the Velcro attachment pads. I was mistakenly sent the 8" Backing Plate (W-65) that did not work.
W-9000 Finishing Pad - Use to apply #26 Yellow Wax 9 (or the like)
W-8000 Polishing Pad - Use to apply #9 Swirl Remover
W-7000 Cutting Pad - Use to apply #2 Fine Cut Cleaner. I don't use this pad on my Impala, as it is a pretty aggressive pad and should only be used with severely oxidized paint.
There is also a W-1000 pad that is essentially the old version of the W-9000 pad. A gallon of #26 Yellow Wax is approximately $31. At any rate the folks at Meguiar’s were always very helpful and properly informed. I can't say the same for the other two vendors I used.
Another wax product that has received good reviews from the WAIL folks is Griots Garage “Best of Show”; supposedly it is easier to work with than the Meguiar’s products.You will be very satisfied with this buffer.
