I used 3000 grid sand paper (dipped in water for 24h. before use) to level touch up paint on my hood. I kept the area and sanding paper wet all the time. Used a block and applied very low pressure. After a while touch up paint leveled but I noticed 2 dark areas. I stopped, cleaned and applied ScratchX 2.0 by hand. I was completely able to remove all sanding marks without using a machine. However I have these spots now. I did very gentle sanding since I could remove sanding marks by hand how could I damage the paint like that? Or is this not a paint damage and will vanish after I polish with rotary?
