There usually isn't a need to sand up to 2000 grit.I only sand up to 320 grit greaseless,then I start buffing.Also make sure that your switching directions 90 degrees between each grit and compound,so you get out marks left from the prevous compound.
Also what buffer are you using,or is it a converted bench grinder?
After I'm done sanding with 320 grit greaseless,then I use black on a spiral sewn,then white on a loose,and I get a mirror like shine.Brown(tripoli) tends to make the aluminum im working with cloudy,so I don't use it.
