The number one confusion when it comes to car care is this: People simply do not know the difference between car polish and car wax. It does not help that companies often mislabel them or combine them into one product. What's worse is that Company A's polish maybe more of a wax while Company B's wax more of a polish.
Most people will simply get confused and won't bother to understand. To illustrate in a bit of hyperbole; think of a polish as sand paper and waxing car as a film of oil on top of your car's paint layer. That should make it clear that its polish that gives your car that coveted showroom shine.
Waxing acts as a sealant and does not smooth down the imperfections of the paint. Polishing on the other hand evens out the surface and "grinds" down the clear top coat layer of the paint to give it a smooth surface. This is what makes your car's reflections attractive and impeccable.
That's not to say waxing should be eliminated. But if you could devout more time to polishing than waxing it just might make your car glow better. An old adage is that: Polishing shines and waxing protects.
