Have had my primer spray on powdery a few times recently, making my models look as if they have blundered into a swarm of bees. Seems to happen mostly with white primer, have had it with different brands.
Any idea what could be causing it?
Maybe you are not Primus inter pares...
I will get my coat...
Not shaking it long and hard enough befire spraying?

Can be caused by spraying from too great a distance, causing the paint to start drying in flight.
Are you in a place with high humidity? Temperature can also be an issue but low has more impact than high.
