Hello, I am currently considering the purchase of a car which is in great shape, subject to one thing. It looks like at some point, probably quite a while ago, it drove through a pool of paint on a roadway at speed which splashed up on one side of its undercarriage. It's kind of a beige. You can't really see it from above or when standing beside the car, but it still bugs me.

Anyone have any ideas how to take this off without damaging the car/undercarriage/etc.?

Or, is this even something I should care about? FYI, it is a Porsche 911 Turbo.
