Paint question for you auto guys

You can fix those areas with a polishing kit

Use cloths or pads from 3200 grit to 12000 grit (don't skip any grits), then hit it with auto polish or Novus plastic polishes

You likely should sand those areas with a very fine sandpaper (1500 grit or so) before clearcoating.  Causes could have been getting too far away from surface, or blushing.

Blushing with a lacquer finish is a humidity problem (not common in winter, though).  Lacquer thinner evaporates so fast that cools the paint surface drastically, causing "dew" to form on the surface is the surface temp falls below dew point.
