If I were going to have a bezel restored, I would send it to Randy Combs.
About a year or so ago, I posted photos of two 1970/1971 non-ac dash bezels. The worst one had some adhesive residue where somebody had applied a car show award. There was also some yellowing of the original clear and some very fine scratches where it looks like somebody tried to clean it. The other bezel was a very nice original bezel off a 70K mile car and had some yellowing. I sold the bezel with the adhesive residue to someone who shipped it to Randy for restoration. The post with original photos can be seen here:

These photos show the finished product. The bezel was nice and straight before restoration, it was in excellent condition after restoration.
