Tail Light Clear Coat Polish

So today as a learning project to fixing the crack lines on my spoiler clear coat in the future, I decided to fix up my Tail Light Clear Coat that took the abuse of a Canadian Winter and salt and looked dull and had the same crack lines. Before picture of the tail light: 

 

You see the lines and how dull it is. Hence why I took them off the car and put my all reds back. My weapons of choice: 3m Swirl Remover (get it here!) and 600 grit Sandpaper: 

 

Mothers Powerball (get it here!): 

 

 So wet sand the clear coat down to remove imperfections and for me I used 600 grit as anything higher would not remove the lines / cracks that were in my clear coat: 

 Remember! if you sand to far you may remove all the clear coat. Keep checking to make sure you don't completely remove the clear coat. Once it is sanded and you see the cracks / lines gone and it looks smooth, its time to use the swirl mark remover: Here it is on the sanded part of the tail light: 

I used too much here I think, but oh well :) Then use the Mothers Powerball to shine those tails up real nice. Here's two pics of how clear they are:
