It is not a primer. Use a real spray primer (not GW chaos black or skull white) with some tooth to it and you should be fine.

You probably already know this, but I figured I would throw in my two cents.

Paints are mixed for various qualities: durability, glossy or matte finish, color, thickness, texture, adhesion, etc.

Primers or Undercoats: highly adhesive, they stick to any kind of material. They have very low thickness and apply in thin layers. They have a microscopically rough but generally smooth texture. They are NOT built to be durable or scratch resistant or have a good finish. Primers are meant to bind to any kind of material like wood, plastic, metal, etc. They provide a surface that other paints easily cling to.

Their color doesn't matter much other than to let you know which parts of the model remain un-primed. Many people prefer white, because less base paint is needed on top when saturating a bright color (base paints are slightly transparent in thin layers). Others prefer black, which is especially useful if there are hard-to-reach areas that may not get painted, as they will look shadowed and not be noticed.

Base Paints Fairly durable, apply in a nice even coat, thick enough for their heavy pigments to saturate the surface. Base paints are built to as even and consistent a color as possible to a surface.

Generally plastics are much easier for paint to bind to than metal or resin, especially when scuffed. But as a general rule, your paint will attach more firmly and avoid flaking off if you put a primer first, then a base paint.

No, Mournfang Brown is not a primer.

Would spraying black, then spraying mournfang, hurt the detail on the model?
