I think the PC would waste product. I use the 4" foam Meguiars hand pads. One spritz per panel is all you need once the pad is primed. I just apply to each section and lightly buff it in (without adding more) and it disappears into the paint very quickly, maybe 20-30 seconds max. If you apply it in long, even strokes, it seems to deposit too much product at the point of initial appliction and very little at the other end. If you've ever used Werkstatt's Acrylic Jett, same thing. Any thick spots are tough to remove and with Clear Seal (or for that matter, Optimum's Opti-Seal), thick spots either appear as streaks or don't seem to dry clear and need to be lightly buffed off with an MF towel.
Once you get the hang of it, CS is very easy to use.
