I find those length wise scratches harder to get out for some reason so I avoid those strokes after I am sure I have gone as far as I want with pit removal. They don't look so bad if you get all your scratches out. The finer grit you go to the easier to get to shiny which means less time on the buffer for that phase.
Same. Long, deep scratches are sometimes worse than the original corrosion.
