Hey Mike,
I never did nail done what caused it but suspect it was dust or moisture after application and before it fully cured.
Since then I have polished and corrected the paint a few times and for the most part its all gone.
I've changed from using coatings and now just wash, clay and wax very routinely (4-5X) per year.
Its the easiest and keeps my truck looking great.
Here is a pic of her how she sits today which is a 6 year old paint job.
