Polishing Carbon Fiber Composite

I mentioned a while back that when I received my last CFC order, one sheet i apparently ordered glossy.  I found a YouTube video about polishing CFC.  My, what an improvement!

It turns out that raw CFC can not be polished to that pretty state, at least directly.  I sanded a piece with #60, #120, #320, #600, #5000.  Then I buffed it with the white buffing compound then Mother's Mag Wheel polish.  It looks better but there seemed to be no big gain after #5000 sandpaper.

From what I am reading, after sanding the gloss finish is a clearcoat on top of that beautifully sanded surface.  I may buy the glossy stuff for future parts and use the raw stuff for parts already in process. 

I may have spoken prematurely. I started over and included some #1000 sandpaper this time before moving to the buffing wheel and the polisher. It feels better. Does it look better to you? 
 

In case it is not obvious, i polished the piece with the hole.
