I normally wash my car once a week with the regular two bucket method or the rinseless two bucket method and then waterless wash it two or three times in between. If I prep my car with clay bar and polish could I get away with something like Meguiar's Ultimate Spray Wax and no other wax/sealant? Seeing as how I also use it as a drying aid after I wash the car? It is getting spray wax once or twice a week.
