That "cloudiness" could be anything from something that got on the surface like wax, bird poop, oil, just about anything. The surface of the primer is porus to a certain degree, so little microscopic traces of something that got on it could still be there. Try scrubing it good with a soap and water. If that doesn't work try a "wax and grease remover".

On the other hand, it may not be on the surface at all. What you see could actually be a difference in the substrate it was shot over. If for instance that hood could have had OEM paint or an enamel paint job over the majority of it. Then there are a couple of lacquer primer spots in the middle. Those lacquer primer spots have sucked up solvents out of the DP (epoxy primer) and the top surface IS going to look different. There is nothing you can do about it, short of sanding it and applying another coat or two of DP or other epoxy primer.
If you were to do that, you have MUCH better odds of a nice uniform sheen being you would have a great, cured uniform base.

It could also be different in those areas because the guy how applied didn't apply it evenly and it has thick or thin areas that have a different look. That primer has little to no UV protection, it could be "breaking down" in those areas as well.

More than likely the black epoxy is starting to "chaulk or blush"
If the epoxy has been on the car for 6months or longer and driven everyday, that is whats happening.
If its been on car for a year or longer and car is driven as a weekend car, that would be in the time frame of chaulking.

This is normal with an epoxy, as epoxy has very poor UV protection BUT no damage is done as the outer layer is "dieing"
and all you need to do is sand with 180-400 and shoot another coat and it will be good to go again.

It sounds like its in the beginning stages and i would let it go until
you see some small spots turning white.

agree with Barry,

because the (milky) chalking is on the hood/trunk (most sun exposure) very likely it is UV damage. Look closely, probably a little chalking on the roof also.

Qualifier (?): ok to leave it for now as long as you keep more sun off the car.....

What ever it is, if wax and grease remover won't remove it, better to sand and re-coat with DP

You can shoot a second coat of DP for a "satin" finish but still can't leave it in the sun......
