i send my car for the 2 step polish and wax 2 weeks ago. just yesterday while i was slowly inspecting while waxing my car, i noticed that are 4cm by 4cm patches of rough area (which doesnt shine as well). Has that been missed out during polishing? I tried to put the wax on that area but it doesnt seem to shine nor smooth. how can i remove this rough patches and what product should i use?
