I have always used Autoglym products, that have been very good. About every 3 months I will use their Rapid Aqua wax to add a hard shell shine. However, after just the monthly wash I will go over the car quickly with the Meguiar's waterless. I would never use it without first washing the car normally though, as I would'nt trust the Meguiar's on its own to remove fine dust/grit/sand without scratching. As a finisher though, it is very good.
