Mr.Hobby GSI-B504 Metal Primer Spray - Precision Primer for Metal

Achieving a uniform finish on metal RC parts starts with a suitable primer. The Mr.Hobby GSI-B504 Metal Primer Spray is formulated to improve paint adhesion and aid in producing a neat, durable topcoat.

What the Primer Does

This primer creates a keyed surface that helps prevent flaking and gives the topcoat a more even appearance. It is particularly helpful on parts where durability and detail matter.

Best Practice for Spraying

• Remove grease, fingerprints and dust before applying the primer to ensure full contact.
• Mix the can thoroughly and start with a test spray to check the atomisation.
• Apply several light coats rather than one heavy application to maintain surface detail.

Common Use Cases

Model builders will find this primer useful for reworking wheel hubs, guards, and small metal accessories where a solid paint base is required to withstand handling.
