Best budget

Vallejo Hobby Paint Spray Basic Primer, Grey 400 ml, Perfect Matt and Self Levelling Finish

Vallejo Hobby Paint Spray Basic Primer, Grey 400 ml, a matt, self levelling acrylic spray primer for models.

Our score8.6/10

Primer is the least glamorous coat on any model and arguably the most important. It gives paint a uniform surface to grip, reveals sanding scratches and glue marks while they are still fixable, and evens out the patchwork of plastic, putty, resin, and photo-etch that a finished build actually is. Skipping it is how paint ends up peeling off masking tape. The choices are broader than they look: lacquer primers bite hard and sand beautifully, acrylics are gentler and low-odor, and colors matter, since black, grey, white, and pink undercoats each change how topcoats behave. This guide compares rattle-can and airbrush-ready primers, and explains which chemistry and color to use for your surface and paint system.
