There’s no need to wax every time you wash the car…unless you simply enjoy waxing. The liquid waxes typically are more polymer based, whereas the paste waxes have a high carnauba content. A spray wax like Optimum Car Wax is very quick and relatively easy to use if you wanted to do it more often. Cleaner waxes usually have mild abrasives in them, and I don’t recommend that for the soft NBP paint.
