What is the best way to polish scratches out of paint and plastic ??
a back and forth motion or the circular motion ??

I think back and forth from what i have read. This is suppose to prevent swirls that are more visible :?

If I remember correctly, I think windshields should be cleaned in an up and down manner in order to prevent horizontal lines. It is my understanding horizontal lines may deflect more sunshine into your eyes than the vertical lines will. Of course other brands may differ. Of course this could be an old wives tale too. Who knows??
