Yeah he said he washed it right away, the roof is the worst part. Judging by what he said and what you guys said my guess is brake fluid. Roof is the worst part. The washing seems to have cut its strength, but also spread the damage.
I own a Griot's random orbital. I'm pretty decent at using it, but my car is already near perfect. His paint was not great to begin with, but this just short of ruined it. I like meguir's 105/205 and usually only need a mid/light polishing pad. This is going to need a heavy cutting pad.
Will try to get some better pics today, we are headed up to
http://www.detailing.com/ which just so happens to be 10 minutes from my house(I buy everything there).
Attached is my car, no pro but not bad.
