On rare occasions water in line could cause the clear to "seed up" or if the clear/hardener are bad and even if you let the mixed clear set to long it could begin to react and cause this "seediness" to appear instantly as fisheye/pop bubbles. Most people who put on a first "tack" coat so lightly that these defects can't be seen.
This is just a guess and I hope you get it fixed easily!
Also, did you get the clear completely stired up? I had one guy who would give it a couple of stirs and go spray. All kinds of funny stuff happened!!
Just a thought.
