Wow. one rain event did that to your paint? Your air's pollutants have reacted severely with the waxes you use on the Porsche. My car is parked outside all the time lately and even here in polluted NJ I've never had that issue merely from rainfall.

But I think the Porsche is the least of your issues. If you haven't already I would install some industrial strength filtration for faucets, showerheads and would not cook or brush teeth with anything but bottled water.

I have similar but different issues now living in a 100+ year old building, I don't even drink out of glasses anymore, only disposable recyclable cups. Everytime I wash glassware, even with a PUR filter, the glasses dry with a weird film. I now have to see a dermatologist on a regular basis.
