The Applicator (cool name for a piece of foam) holds only until you stroll a screw or edge, but that should happen more frequently but especially in the care of stainless-prone locations (door or fender edges inside of the engine compartment). Since it does an effective sponge cut better in 3 flat parts for a fraction of the price. I got the "Applicator" with a set get, individually, I would not buy it!
