The best way I've found is to use 3M rubbing compound and then finish it off with a really good polish called "Finessit" also by 3M.  Car painting supplies have most 3M things and it's available at West Marine/Port Supply.  There was a system a friend of mine use to do in acrylic coatings that did a super job, and being acrylic, it naturally had good UV resistance.  But he got out of that and went back to rocket science (really) at Lawrence Livermore.  I guess the latest and greatest weapons pays better than boat buffing.  Go figure.

 

Once the surface has been broken though, you will never get the gloss back to where it was nor will it stay glossy for very long.

 

A 32 oz framing hammer works well on the wasps but you need to know somebody that's good with dings before you do that.
