Good primer, but just know ahead of time that the color is pretty light for a grey. It's actually lighter/whiter than Vallejo's Model Color 70.990 Light Grey. Be careful about choosing this as the primer if you are looking for darker grey colors (or as was to my surprise when I started using it, regular grey colors) as this will look closer to white than to grey.

Typical Vallejo product which is excellent. This primer gives great coverage, and won't hide details. This runs through my airbrush without a problem when thinned with Vallejo thinner.
