Hey guys,
  I made a made out of my solo cowl for my motorcycle and I had to sand down a little alligatoring.  After sanding it down, I went with 220->400->800->1000.  Then I used turtle wax rubbing compound followed by meguiars gold carnauba wax.  After all that, the part is still dull and doesn't look at all like it helped.

What am I doing wrong?

Thanks in advance

Rubbing compounds vary greatly in their grit, it's probably fairly course and most will give a very haizy finish.  Need to follow it up with at least a polish, you can stop there or follow that up with a machine glaze to yield a brilliant finish. Would probably do sanding discs on a foam interface 2000 grit wet, 3000 trizact or light cut rubbing compound, polish, glaze.
