Using black primer allows you to more easily create contrast with paint. Since miniatures are so miniature, contrast is really important. A nice black primer lets you paint “up” from your shadows using lighter colors, instead of applying shadows atop your light colors (as is the case when applying washes or inks). The shadows are more or less taken care of already; your job is to use color and highlights to bring depth to your model.

You can dilute water-soluble surface primers with a little water to help it flow off your brush onto the miniature surface. Just don’t use too much.
What happens when primer dries?
Disrupting the primer film as it dries will leads to an uneven, textured primed surface. Worse yet, the primer may develop brush streaks, bubbles, or warped edges as it dries. This ultimately leads to a more difficult paint job on the model, as well conceals the other fine details on a model’s surface.

Spraying a primer allows you to apply very thin coats on the surface of a model, evenly. This prevents the primer from pooling on a model, avoids the formation of bubbles, and helps to retain miniature detail and texture.
Why is my primer peeling?
In high humidity (e.g., a lot of water moisture in the air), is primer clumping aka orange peel. The water in the air mixes or dissolves in the small spray droplets and causes them to coagulate together. As the primer travels to your model, those large clumps of primer/water dry as a bumpy texture–which appears like the skin surface of an orange.
