Im thinking of using one of those hand applicators (Polishin Pal, adams blue hex grip) to help with polishing and waxing by hand. Previous attempts at hand waxing I used those yellow round foam pads. Ive always gone in circular motions with these. Is there a "correct" way to use the hand applicators like the Polishin Pal? Ive seen mentions of going side to side, and another post saying it doesnt matter which way. Thanks guys.
