Chances are very high those spots are where you or someone sanded or buffed through the clear coat. The base coat has no UV protection and it will chalk if it isn't protected. Solution in that case is to color sand the area (to remove the base coats oxidation) and re-clear the panel. Good rule of thumb... If you're going to color sand a clear coat you need at least three coats of clear, and four is better.

I have had this before. It is very small craters in the paint, usually caused by moisture in the line while the paint was shot. Then when you went to sand and buff the residue settles in the craters. Take a tooth pick and see if you can clean out the crater and remove the white residual. If not then it is in the clear and would have to be sanded out and recleared. If they are small enough and do clean out with the tooth pick you can spot them in with clear, resand and buff.
I had that on this trunk and here is the final result after some work.

If it is not little craters then it has to be something in the clear or even on the black base coat. 2 stage is way easier than single, but if you get something on the base before clear it will show up. If you get trash while you shoot the clear it will show up. Plus you are doing black, by FAR the most difficult paint to get right. Did you do anything to the base before shooting the clear? Sand ? Wipe?

i would suggest buying a microscope like this, http://www.radioshack.com/product/index.jsp?productId=2179604, and actually see what the white spots are. i have one like it that i have used for the past 30 years on paint problems. look at the spots with the microscope ans see what they look like. maybe pick at one spot with a razor blade for a more detailed look. if you are careful you will not see the damage from the blade. of give the spot a quick touch up. with your description the spots sound like moisture in the clear. i have seen this a LOT in paint jobs done in a air dry situation. heated air out of a machine can cause condensation in the lines by the time it makes it to the spray gun. also moisture can form on the cars surface if the temp changes while you are painting. maybe call the place where you bought the paint from and ask for some help from the paint rep. this is the reps job to help out with problems like that.

Research "solvent pop"
Sounds like what you have.
Has to do with the paint and painting method
