yeah for mine, on my 89 carrera, that was a brand new factory fan we vapor blasted it and that's what the natural metal finish looked like, not even/painted look. I think it's cool and we just sealed it in with clear.
I have no idea what a 993 fan would look like with the same process. Pretty sure they are painted or coated in some way from the factory as mine had a little chipping. So, a PVD type coating in the factory finish would be fine and give you that natural aluminum type look

Yes the shroud is also magnesium. A friend dropped his and knocked a corner off, he was lucky to find a welding magician who fixed it. We both used POR15 detail cast iron paint after vapour blast and primer. No photo but still looks good after 2 yrs all weather use.

Thanks for the input all and for the steer towards the original coating being Chromate.
I have found a local magnesium specialist who can re-chromate for me. He said due to some changes in the chemical process due to legislation over the years, it is possible the finish may be a different tone to that produced 20 years ago. I said so long as it is flat grey I am happy. Once done he suggested locking it in with satin clear coat to preserve.
