Heater control bezel restore

The inst' bezel was a white abs plastic. It's my understanding that primer and/or preheating for the vacuum metalized chrome turned the plastic yellow. If you pull that inst' panel you will find a heck of a lot whiter backside.
I don't believe any climate bezels left the factory with that camouflage finish.
They used a grey and black abs plastics too. That's why I suggested regrind at that heater bezel. I can't say what parts were vacuum metalized bright chrome and what parts were painted argent in every model. Even some pot metal parts would change from chrome plated to argent paint with year model.
I know that all vacuum dispersion chrome would disappear into the wind over time. I've also read that the chrome didn't bond well to anything other than virgin material. Maybe that's why some parts have a coat of lacquer for primer underneath the chrome. I know paint doesn't take to the wind and leave like the chrome does/did. We can see that the black and white paints didn't leave. I'm theorizing and pretty much convincing myself that all 3 of your dash plastics were once vacuum metalized chrome.
Why the radio bezel isn't bright chrome but seems to have held up better may boil down to the plastic it's made of. Maybe a previous owner painted or replaced it.
I can tell you that sending the 3 bezels out for restore ( strip, rechrome, repaint ) would be expensive. Very few vendors of this service left today. EPA regulations and Chinese reproductions are to blame.
Some members/owner have done a decent job of DIY paint renew using spray bomb chrome, etc. It's tedious labor. Liquid mask instead of tape and other tips will help.
