Apply the Fine Clay Bar to the surface and rub the clay back and forth with very light pressure. If the paint is dirty, you will actually feel and hear it working. Keep moving in a light motion till you no longer hear or feel it working on the car.
If the Boss Gloss begins to dry, you'll need to spray more on. Please note that our Fine Clay Bar is fairly sticky and cannot be used on a dry surface. If it's dry, you'll make a mess and potentially damage your paint, so always make sure there is ample lubrication on your paint.
