Zaino Polish
I actually have no experience with the Zaino yet, so I'm basing my opinion on what I've read online. I've got a bunch of bottles sitting in my office and my car just arrived in port on Tuesday. I'll check out the removal process and see if a PC would be effective. Here's what the Zaino folks say about using one:
Q: Can I use an orbital polisher to apply/remove Zaino polish?
A: Yes, you can use an orbital to apply Zaino Z-2, Z-3, or Z-5. I don't recommend it because you waste too much polish that way. The pad on an eleven inch polisher can absorb almost enough polish to coat your entire vehicle. Each time you use an orbital to apply Zaino polish, you are probably wasting as much polish, if not more than you actually applied to the car.
Zaino polish applies easily by hand, especially if you dampen the aplicator pad with water and spritz it with Z-6 before applying it.
If you use an orbital to remove the residue, you should place a white, 100% cotton towel between the pad and the paint, and keep it turned and refolded often so that you are removing the residue with a clean section of towel all the time.
Note: A single orbital pad WILL NOT remove the polish residue from an entire vehicle. You will have smears if you don't use a towel and turn and refold it frequently.
