Rarly

I have had pretty good luck painting the chrome plated (or whatever it is) aluminum over powder coating that had worn through some. Clean it well, mask everything off, and spray on some Bulldog Adhesion Promoter. Let it dry (or whateveer its directions say), and then use a suitable black paint (like Rustoleum flat black).

I got maybe 8 good years from powder coating this shiny aluminum trim, but it weathered off in places, and at 15 years looked somewhat ratty. Most notably the horizontal flat strip along the top of the door skin, but these windows were showing their skirts in places. Maybe it was because I didn't do anything special as prep work. But you have to disassemble everything to powder coat because of the heat and so on. Which you can do - of course, the little screws can act up or be rusted, and getting the rubber and glass back in I recall taking some patience.

Paint is much easier, and you can touch it up pretty well from time to time as small bits are rubbed or nicked off.

Anodizing is nice, but it bleaches out in the sun to a purple (at least up in my rarified atmosphere at 5,000 feet and above). Nothing is easy.

Maybe one of the used Porsche parts sellers will sell you just the hinges?

Though looking at that gorgeous car maybe you want to have a professional prep and powder coat so it is up the the standard of the rest?
