Ok I was away on business for 2 weeks during that time the water heater blew in the house and had to replaced. My wife parked my 91 BMW 325I cabrio, 4 month old paint by the way, outside overnight. When she goes to pull it back in around noon the next day shes sees that there dried EGG all over the trunk and some on the hood. I have taught her enough that she washed the car as soon as she saw it with CG wash and gloss. But it was still stained. I came back yesterday and tried clay bar and some menzema polish and CG pro polish 3n, by hand, and nothing touched it. Is there any better ideas? Does it need a sanding? any help would be great.
