Radio bezel restoration

After years of looking, I’m finally getting a used bezel for the dash! In order to restore it, I have a few questions.
Is the chrome on the plastic an actual chrome plating process or chrome paint?
Would the non-chrome silver areas be the often-used argent silver?
Are the black surfaces all the same black for the grain(shiny) and non-grain surfaces? Which black?
What color for the white?
Thanks for the help. If I find it too daunting, is there someone that can restore it for me?
