I have tried to restore Barracuda -70 tail lights and the front parking/turn lights. The paint has a very hard surface. Not that affected by paint stripper. Even tried acid dip. The acid eats the metal but not the paint. The silver is more reflecting and vivid than the paints I have used.
Kind of feels like powder coating. I would like to try powder coating. Mask the outside, put the powder on and put it in an oven.
