Mr.Hobby GSI-B506 Surface No.500: Primer for Smooth Model Finishes

Model builders and RC hobbyists rely on a consistent basecoat to get clean paint results. The Mr.Hobby GSI-B506 Surface No.500 primer spray creates a uniform surface that helps paint lie flat, making it easier to achieve crisp detail on plastic and resin parts.

Advantages for RC Model Preparation

The GSI-B506 formula is tuned to settle into small flaws and create a level layer without obscuring fine details. It works well on common hobby materials, helping reduce sanding effort and improving final paint adhesion for bodies and scale parts.

Practical Application Advice

Start with a clean, degreased model and shake the can thoroughly before use. Apply several light coats rather than one heavy pass, keeping the nozzle steady to avoid runs. Let each coat dry fully before sanding or adding more primer for the best result.
