My suspicion is that the piece under the paint issue is rusting, causing the paint to be that way.
Leading evidence: 'rusting, causing the paint' (1 discussions report identifying this cause; no attributable repair resolution). Across 1 matching discussions, the most frequently mentioned possible cause is 'rusting, causing the paint' (1 discussions; 1 report identifying it and 0 suggest it). No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

hey all
I tried googling this but got nowhere. My suspicion is that the piece under the paint issue is rusting, causing the paint to be that way. Is there a replacement for the rusted part? Thanks
What? What? No. Either something dripped on there or a bird pooped on your engine lid and it ruined the paint. But what I have to ask is - if you think something is rusting underneath the louvers on your engine lid, why do you not lift it up and check it, and possibly correct it????? This makes no sense........
Or it could be the other way around as Joe mentioned. Some kind of strong chemical (e.g. solvent, acid, etc.) dripped on the spoiler grille and promoted rust underneath on the hinges. You should disassemble the upper section (i.e. grille), repaint, and remove the rust on the hinges and repaint those. If not, it's only going to get worse. But again, I don't think it's coming from below.
Bird poop jokes aside, I started a thread about this a long time ago and never really came to a solid conclusion. I tried multiple products to take off the stain but nothing really worked.

Bird poop isn't necessarily a joke -- it's highly acidic, so it can etch into the clear coat if it sits there long enough. I had that problem with an X5 that sat outside. Sealing the car with something like Opti-seal helps prevent the clear coat from being penetrated. Given that the OP's spot is in the same exact area as yours, it must be coming from the engine. Ethyl Glycol doesn't typically damage paint, but maybe there's more chemicals in Porsche coolant. Brake fluid can damage the paint.
If an abrasive like rubbing compound didn't work, then it seems like whatever it is has penetrated the clear coat. The only thing I can think of beyond compound is something like Iron-X which pulls contaminants out of the paint. It mostly pulls iron particles out, so it may not do anything, but maybe worth a "Hail Mary" try. If that doesn't work, maybe try a clay bar (but this is another Hail Mary attempt and should be done last).
Second this. I had a seagull with stomach issue sit on the hood of my VW and crap all over it. I got rid of the bird and cleaned the hood as soon as I noticed, within a couple hours max. Shortly after the clearcoat started lifting where I had removed the birdcrap. It continued to get worse and now needs a repaint.
