Yesterday I worked my roof with the G110V2 and Ultimate Compound, paying close attention to rotation speed, speed of movement and pressure. I don;t have any major scratches on the roof but a few minor ones that I am pretty picky about. But the G110V2 did not even make a dent in the appearance of these fine scratches. I worked a few areas using different techniques. Finally I resorted to Ultimate Compound followed by M205. Still no improvement. While the roof is very shiny and smooth as glass the fine scratches are still there starring at me. What should i go with next M105? by hand? by DA? or are their other recommended compounds in between.
