True polishes have cut, some finer than others. You can always tell if a product has cut because it will powder.
There are some badged polishes like the Meguiars DC2 for example that are branded as polishes but have no cut.
Although to make things more confusing the Megs DC2 is actually a glaze.
There are products out there such as the Sonus P21 paint cleanser that are chemical cleaners that cleanse the paint withou any cut of the surface...
Hope this helps
