OK OK OK OK already ;-).  I have no clue what it was.  To offer an hypothesis
that might support the acid rain theory (or any other dissolved corrosive):
 As the water evaporates, the concentration of the dissolved content
increases.  This explains the ring-shaped etching in the paint.  These ring
shapes are the resultant shape of the last traces of moisture as the water
evaporates.  While this concentration is increasing after the thunderstorm,
it's sitting in the hot sun with temperatures (on the car's surface) well in
excess of 120F.  We're all aware of the "10 degree temp increase doubles the
rate of the chemical reaction" bit.  But it could have been anything.

I do know that the damage was gradual over several months, my car is only
exposed at home, which is FAR away from any industry, and now it's protected
by poly-whatever and is also now in a garage at home, so my problem is solved.

Again - I didn't mean to start a fuss over acid rain.  I just wanted to
let people know that their car might be suffering the same damage.

I haven't noticed it on any other cars.  Maybe Nissan just gave me bum paint?

Nope - no sap ever hit it.  Sap doesn't etch paint.

Cheers.  And wax your car.
