I have a PC with these pads, new to it so sorry if its a daft question! I notice the orange pad in particular is quite hard, not too flexy. Presume thsi is for heavier swirl removers and cuting compounds? But I also noticed having used the orange and gree pads the other day, that when I washed them out, they are all soft when wet. May seem obvious, but question is, should you use them "wet" (like a bodyshop polishing mop) or dry as they are, save for the polish?
