# Best Model Primers: Surface Prep That Makes Every Paint Job Better Source: https://modelbuildlab.com/best/best-model-primers Updated: 2026-09-15 Publisher: Model Build Lab. Our score is an editorial rating out of 10 (fit 35%, features 25%, build 20%, value 20%), not a customer rating. Method: https://modelbuildlab.com/how-we-research#our-score 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. ## Picks ### 1.
