      IT can be done if you have patience. When doing custom work to achieve great results-Keep saying to yourself IF ITS NOT PERFECT ITS NOT RIGHT. I would not use fiberglass for that project. When working with plastic like your stock bezel , I would use ABS plastic .....first cut a piece of ABS to fit around the radio filling in the gaps, Remember if its not perfect its not right......when th piece is right CA glue th new trim ring to the stock bezel making sure it is flush..Next apply a little body filler on the seam where the new trim ring and the stock bezel meet. Sand the body filler down until its PERFECT .Finally sand, prep, and paint..............Good luck  

okay cool so basicly take my time and get it right. wont the filler crack due vibration and the different heats it will experiance?

   IF you take the time to make sure the two pieces are perfectly flush when CA gluing , you will use hardly any body filler, And you will sand away 95% of it ,so cracking shouldnt be much of a future issue.........post pics when finished......good luck
