Just my preference, I don't use wax based products. IMHO, there are better products developed today that are longer lasting and to an extent, easier to apply than wax. Wax can trap dirt and doesn't dry hard like the more modern chemical polymer sealants.
To each their own, I use clay bars and top with ZAINO products.

Good luck, you'll find your own preferences to keep your car looking great.
