Show Room New Glass Finish
I purchased the NewGlass2 ( www.newglass2.com ) Fiberglass Beautifier and Protector.  Here is the process and results.

Before

I totally wet sanded the entire boat with 600 grit sandpaper.

        
   Coat One               Coat Two             Coat Three            Coat Four    
       
Finished

Overall it was easy to apply... it takes just 30-40 seconds (not minutes) between coats... make sure to smooth out any runs or drips before it hardens.

Spinnaker Testing

First time using the spinnaker... and yes the spinnaker will move the boat with the trailer... much to my surprise.
Since the X is a cruiser not a racer, I sold the spinnaker.

Winter Storage

The cover was about $150 from Overtons... heavy duty, silver on one side black on the other... strong grommets.
