Use all. First 220, 320, 400, 600, 1500. The higher grit makes it more shine and is a smooth finishing touch on a metal but I’m not sure on plastic. ---

Skip the 600 and 1500. Just use the 220, then the 320, then the 400 and you’ll be good. ---

Just use the 220. Any higher and you won’t get the results you’ll want. ---

anything above 400 pretty much just makes it shinier/grind worse. so I’d go up to 400 at the most. you’d be fine with the 320 or 220 though. ---

What!?! 150 - 200 is a good grit… ---

I used 180 on my starlite + 2 rubber o rings per half (4 total) for some added weight and it now grinds quite well.
