This may be a rookie question that's why I posted it in here, but last year I detailed 2 black cars and on both with my orbital polisher I tried to polish out some pretty harsh surface scratches to the point where both looked almost grey. One was a 2014 mustang and the other was a 2010 Camaro. Anyway the point of this is that after I ran over the cars with compound and moved into polish I could see tiny little scratches all over the place. I don't know if I didn't decontaminate the car good enough or what but what causes this? I cleaned everything and ran over the area with clay again and tried again, but the same result... I even tried a fresh pad! I don't know why this happened and was super confused does anyone have any ideas on what this could have been?
