Help! I'm refinishing my hardwood floors myself and wondering what the best next step is! I used a drum sander and edger (grit 36 then 60, 3 layers of each) to get to the bare wood. But I have these wide white scuff marks where the edger met the drum sander. Will they go away when I sand with the 80 grit and buff or do I need to sand more at the 36 grit to get rid of them? Thanks for the help!!

Sand to 100 grit for best results.

it's normal, just sand with 100/120 next, last
