My wife and I wound up trading our 2014 Subaru Forester in to a Mercedes dealer sight unseen. My wife explained that I'm an obsessive amateur detailer and they can be assured that the car is in awesome shape. She failed to mention that this car is like the shoemakers children....it never gets detailed! It's being turned in next week and I have to give it a quick and decent detail. I'm not a one step kind of person, but in this case, I need to do it. I'm going to place an order for either HD Speed or Menzerna One Step today, or something else if need be. Which would everybody recommend, mainly for ease of use? And am I better off to use my Flex 3401 or Rupes 21? Which pads for a one step? Any and all help is greatly appreciated! Thanks in advance.
