Pad rotation isn't vitaly important when applying a finishing wax. It is if you're doing correction work with a one-step cleaner/wax but not if you're just applying a wax or sealant to a finish already in excellent condition.
I use a soft wax pad on put any of the DA Polishers on the 4.0 to 5.0 speed setting. I find the 3.0 to underpowered and foam pads feel squishy like they're dragging behind the polisher as I move it over the paint.
Also, unlike defect removal steps you can tackle as large an area as you can reach or you have enough product to maintain a wet-film on the surface s you're making passes.
A forum friend shared this technique to check how much product is still on the pad and that was to touch the pad down on one of the windows as this will indicate how much product is on the face of the pad. (Make sure the windows are clean of course).
You want to apply a thin coating but should always see a wet film of product behind your path-of-travel... Wet film behind your path-of-travel
