[QUOTE=001mustang]I've used 2200 before and could not tell difference compared to 1600 after 3m 5973 compound then polish. I just compared w/ my untrained naked eye.
No down side to working up to 3000 other than time and money.[/QUOT
You can buff out 1500 grit scratches the only difference it that it takes a lot more work when you finish with 3000 a light cut is all thats needed
