This is from a person who knows his stuff:
"wash then wax - great advice, best thing you can do for your paint. Next, polishes contain abrasives, but polishes contain no nutrients and paint cannot be nourished per se.
The abrasives in polishes work against oxidation by removing the oxidation and restoring a nice smooth surface. However, if you continue to use a polish on a regular basis, you will soon polish your way right through the clear coat (if you're paint is clear coated) and start removing your paint. If your buffing towel or cloth comes away with any "color" to it, you are already cutting into the paint. 1-2 times per year is the most you should use any polish, glaze or "cleaner wax" formulation. There is limited benefit to apply two
coats of wax because you will have the same amount of wax on your paint after the first coat as the second coat if you apply it the same day.
The amount of wax you can apply is dictated by the paint's loading capacity. Let me explain.
Each painted surface has a maximum loading capacity which is the surface's ability to hold a quantity of wax. The loading capacity varies based upon the roughness of the surface (one factor). Unless you are a bigger miser than me, you will surely exceed that loading capacity with your first application of wax following a washing. Everything that you buff off the paint is wax which is in excess of the surface's loading
capacity. The only advantage to applying a second coat of wax is that you might miss a spot on the first application, and you'll probably not miss that spot twice."
