My otherwise spotless jag has two nickel sized blemishes in the paint. One on the roof, and one on the trunk. Other than these, the car is free from scratches, dents and dings. I uploaded a photo of one of the spots for you guys to see if anyone could possibly know the cause. I suspect bird droppings, however it really is a deep and coarse spot that is crackly like an egg.
Its been on the car for a while and it doesn't appear to be spreading. Anyone ever deal with one of these?

 

That looks like bird crap that was left on too long and the sun baked it. If it is crackly feeling than it has affected the clear coat. Sadly the only way to fix that would be either wet sanding or most likely repainting. Since it has affected the clear coat there is not much else you can do.
