Use polish to smooth out the paint
The reason for using polish is to smooth the surface of the paint, which will make it shine and help your car look like new. Some polishes available contain wax, which also help protect the paint, but the wax doesn't smooth the paint itself. When you polish your paint, if you know how to, you can use an oscillating polishing machine. The professionals use a rotating polishing machine, which works faster but will harm the paint if not used in the right way. If you are not a professional (most likely), oscillating buffers are more forgiving.
To measure their results, a good car detailer will hold a ruler perpendicular to the surface of the car and see how far its reflection stretches across the car. The higher the number they can read on the ruler, the glossier the paint and better the finish.
Wax will protect paint
New cars have a clear coat when they leave the factory, but that coat wears off over time and leaves the paint to fend for itself against the elements. That is where wax will help. Wax is sacrificial and will wear off your cars surface over the course of a few months, but in that time it will absorb stains and small scratches before those hazards make it to the paint. The older generation prefers paste wax, while the younger generation like liquids.
The choice is simply personal preference as both products do the job equally as well. Finally, the professional car detailers usually use two coats of wax; the purpose of the second coat is to cover areas on the car that the first might have missed. Do not waste your time trying to apply more than two coats coats for added protection. They do not adhere to the paint and will be wiped off when the car is buffed.
Wax when the seasons change
In between paint cleanings and wax applications, you will find you have picked up stains and scratches. Using liquid spray wax that can touch up stains and scratches between your waxings is a good idea but not a substitute for a real wax coating. Because there is no definitive way to tell when wax has worn off, it is recommended that you stick to a regular schedule: Give your car a wax job every change in season if the vehicle spends every day outdoors.
