I followed with a quick rinse using DI water to make sure no salts are left. Use compressed air to dry, don't let it air dry cause even DI water will spot a little. Also, it was a bit trial and error for me,,, I wouldn't start with a NOS unit. Practice on a used unit to see if you can bring back some of the shine.

^ Thanks .
Would you be willing to part with the Left Side housing? Or both? These are correct Italian housings and I’m in the process of restoring my ‘72 Italian delivered Targa S, from Centro Balduina Porsche Rome. I have the right hand housing but not the left. When imported into the US in ‘78 the housings were swapped to US spec units. I have the three original units but sure would love to have the left. Tyler

Reviving this thread...
Back to the question about the finish on the insides of Italian front housings - I doubt the one pictured in post #1 is oxidized because if you compare with Jaudette's pictures in post #2, you'll see the outside of the housing is very weathered and worn whereas the inside still has some remnant of bright silver with some bubbling here and there.
My NOS front right is Italian and it looks exactly the same as the one in post # 1, clean matte everywhere with no bubbling.
I could be wrong but I think the matte finish was for the Italian market because their front lenses were clear transparent (bright silver would be too bright for clear lenses)
Just my 2 cents.
Matte finish too..

My car is indeed Italian delivery..
